How To Fix 500 Internal Server Errors

How To Fix 500 Internal Server Errors

If You’re Trying to Load a Page with a 500 Internal Server Error:

1. Refresh The Page.

Although it may seem obvious, if the problem is temporary, you might be able to fix it by refreshing the page. Reload the page to see if it works before you try any other items in this list.

2. Come Back Later.

The error is server-side, so I am willing to wager that website owners are trying to fix it as soon as possible. Give it a while, or for as long as an hour, then reload your URL to see if the developers have fixed the problem.

3. Delete Your Browser’s Vookies.

You might also try to delete your browser’s cookies if clearing the browser history fails. If cookies are linked to the error-prone website, you might be able to reload them by deleting them.

4. Paste Your URL Into The Website “Down for Everyone or Just Me.”

Head to downforeveryoneorjustme.com and paste in the URL where you see the internal server error. Either the website is down only for you, or the website is down all the time.

This will help you to determine if it is a problem with your server.

If the 500 Internal Server Error is on Your Own Website:

1. Deactivate A Theme or Plug-in.

Deactivate a plugin or theme

Your current server configuration might be affected by new software, add-ons or third-party programs. You can identify the cause of your internal server error by carefully deactivating and uninstalling each add-on.

This is possible with plug-ins if you have a WordPress site. Select Plug-ins > Installed plug-ins from your dashboard.

Then, deactivate the first plug-in. If the error disappears, it means that the plug-in is the problem. Reactivate the first plug-in, then repeat this deactivate-reactivate process one at a time for all plug-ins to determine which ones are causing your error.

It might be that you find it easier to run your site with fewer plug-ins.

Alternately, your existing plug-ins and themes may not work with the latest software upgrade. To find the root cause of the problem, you can deactivate plug-ins and themes one by one until it disappears.

2. Use a Plug-in Like WP Debugging To Identify The Issue.

Use a Plugin Like WP Debugging To Identify The Issue.

Consider installing a plug-in if your site is powered by WordPress and you are familiar with WordPress debugging procedures.
WP Debugging is a plug-in that helps you identify the problem with your site. This will allow for a faster fix.

3. Make Sure Your PHP Configuration is Correct

To resolve an issue that is caused by a PHP timeout, you might consider adding timeout rules to your script or error handling to address the problem.

A file or folder containing a script such as a PHP script or CGI script may not have the correct permissions. Make sure to check your permissions on your server and that they are correct.

4. Check The Code of Your Site’s .htaccess File.

Check the code for your site's .htaccess file.

500 Internal error could be caused by incorrect coding or a poorly structured .htaccess file. You can manage the number of resources that should be kept in a browser’s cache by using the .htaccess file. If you are getting 500 internal server errors, edit the file.

Access your website files via FTP/SFTP or a file manager such as cPanel to locate your .htaccess. It will likely be in your public_html folder. It is possible that your server will hide the file by default. To see it, you will need to toggle hidden files.

An internal error 500 can also be caused by code errors in .htaccess or custom scripts.

5. Make Sure Your Software is Correctly Installed

Check to make sure that your software was installed correctly or updated properly. For instructions on how to refresh your software, visit the vendor’s site.

Error 503

An Overview of HTTP Status Codes

Web servers that host web pages listen to requests from clients, also known by clients. To communicate back, the server uses several different status codes.

These codes can be broken down into classes by the first number in the code.

  • 1xx: Information – The server is still processing your request
  • 2xx: Success – The request was successful and the server responded with the page or resource
  • 3xx: Redirection – The page or resource has been moved, and the server will respond with its new address
  • 4xx: Client error – There is an error in the request made by the browser or device
  • 5xx: Server error – There is an error with your server

The two last digits of every HTTP status code indicate a specific status for each class. For example, 301 indicates that a page/resource has been moved permanently, while 302 signifies that the move was temporary.

Status codes are almost always ignored. This is fine as it indicates that everything is working. You’ll notice the status code only once you reach the 4xx-5xx range.

What Does The 503 Error Code Mean?

What does the 503 error code mean

As stated above, 5xx status codes indicate that there is a problem with your server.

A 503 Service Not Available error indicates that the resource or page is not available. A server could return a 503 Service Unavailable error for many reasons, including maintenance, a bug or a sudden surge in traffic.

The 503 error message sent can differ depending on the server from which it is coming. Here are some common messages you will see:

  • 503 Service Not Available
  • Temporarily unavailable 503 service
  • HTTP Server Error 503
  • HTTP Error 503
  • Error 503 Service Unavailable

This is a temporary problem: The server cannot service your request because of the maintenance downtime, capacity problems, or both. Please try again later.

No matter what the cause of the 503 error is, it’s usually temporary. The server will restart, and traffic will stop.

How To Fix 503 Status Unavailable

The 5xx status codes indicate that the error is server-side, and there aren’t any direct actions you can take.

Although 503 errors are often temporary, there are still things you can do while they are gone.

Refresh the Page

Sometimes, the error is so brief that it is possible to refresh the page by pressing Ctrl – R on Windows and Linux. To refresh the page, simply open the page and press Ctrl-R on Windows or Linux. Or Cmd-R on macOS.

See if the Page is Down For Other People

Next, you can use It Down Right Now to check if others are experiencing the same error. To see if others are experiencing the same error, you can use Down For Everyone or Just Me.

Simply go to one of these sites and type in the URL for your page.

To see if the URL is received, the service will ping it. It will then display some stats and graphs on the page.

Scroll down to see comments left by others. This can help you determine if the error is only affecting specific regions or devices.

Restart Your Router

Sometimes, the problem is caused by a DNS server malfunction.

DNS stands for Domain Name System and acts as a translator between IP addresses, human-readable URLs, and DNS.

You can, for example, visit Google by either entering its long IP address (172.217.25.206) or simply typing the URL www.google.com.

It is a DNS that, usually hosted on a server, handles all the behind-the-scenes work.

This means that many routers store DNS server responses (www.google.com 172.217.25.206). Sometimes, however, this cache can become corrupted and lead to errors.

Restarting your router is an easy way to clear the cache. After unplugging your router for 5 seconds, plug it back into the power supply.

After a few minutes, it should reboot, and all your devices should be able to reconnect automatically. You can visit the site again once they restart.

How to solve a 503 Status Unavailable error as the site's owner

There are a few things you can do if the site is returning 503 errors.

These are some tips to help you get started.

Restart The Server

It’s not easy to develop – even a static page can have many moving parts, making it difficult to pinpoint the problem.

Sometimes, it is best to reboot the server to see if the problem goes away.

There are many ways to restart your server. However, you can usually access it via your provider’s dashboard. You can also SSH into your server and run a restart command.

After a few minutes, the server should reboot. You can check if everything is running automatically by setting it to boot.

Check The Server Logs

Next, check the logs.

Depending on the service you are running, the location of your server logs may vary. However, they are often located in /var/log.

Look around the directory to see if anything is missing. Run man program_name to check the manual.

Check If There’s Ongoing Automated Maintenance

Many service providers offer automatic package updates and maintenance. This is usually a good thing, as they are often performed during downtime and ensure that everything is up to date.

These scheduled maintenance sessions can sometimes cause 503 errors.

Some hosting companies that specialize in WordPress hosting will automatically update WordPress whenever there is a new version. WordPress returns an error 503 Service Unavailable whenever it is updated.

You can check with your service provider to determine if the 503 error was caused by scheduled maintenance.

Check Your Server’s Firewall Settings

503 Service Unavailable errors can sometimes be caused by a misconfigured firewall. This allows connections to pass but fails to return to the client.

You might need to adjust your firewall settings for CDN. Multiple connections from just a few IP addresses could be misinterpreted as DDoS attacks.

There are many factors that will affect the way you adjust your firewall’s settings. To see the best places to configure your firewall, take a look at your service provider’s dashboards and your pipeline.

Check The Code

Bugs, like errors, happen. It’s impossible to catch all of them, no matter how hard you try. Sometimes one may slip through and cause an error 503.

If your site still displays a 503 Service Not Available error after you have tried all other options, it could be the code.

You should inspect any server-side code and be especially attentive to regular expressions. A small regex bug caused an enormous spike in CPU usage and rolling outages. This led to three days of panic at freeCodeCamp.

You can hopefully find the culprit and fix it, and then everything will return to normal.
