Steps to fix 502 errors in WordPress:
502 bad gateway usually occurred due to connectivity issues and server problems. However, it can quickly deal with sometimes on your own. Now let’s check out a few easy ways to fix the errors.
● Firstly try to refresh and reload your page by clicking on f5 (ctrl f5). This is one of the easiest ways to fix 502 errors. Initially, wait for one minute or so to detect 502 errors and then start reloading the page.
● It can be caused simply due to the overloaded server or the host, and later the sight is returned right back.
● Clearing your cache can be a second useful method to solve the issue, as clearing the cache can be very handy when you come across these errors.
● Further, this error can be caused due to the DNS issue, occurred when you have just altered the WordPress host. In this case, you have to wait until the host is fully functional and adjusted, which in some cases might take 24 hours.
● You can start by simply clearing the local DNS cache, which is similar to clearing the cache. And also, by changing the DNS server, where ISP usually specifies DNS servers, but you can temporarily change the server.
● Errors can sometimes show up because of web host issues, where an action or a request if taken too long to process, will be canceled by the host. In this case, it is recommended to check the support ticket or the host’s status.
● Sometimes the issue can be faced due to the Content delivery network (CDN) or usually known as a firewall. It is suggested to simply disable the CDN connection for a temporary period. You can also disable the plugin of your site.
● Usually, the errors are triggered when there is the cancellation of queries or requests that take too much amount of time to load or sometimes bad coding. Hence switching off the plugins is the very solution for this.
● Examining the logs is another way to fix things, especially helpful in spotting the issue as in where exactly is it situated and also determine the cause, whether from the plugin of your site or due to a web host. And lastly, troubleshooting the issue.
● If you are still not dealt with the issues, then you can actually try restarting the PHP. In case your web host is unable to fix this, then you can get assistance from a support ticket and ask for restarting PHP.
● Lastly, if you are dealing with a large amount of WordPress imports, then you will come across the PHP timeout issue. Errors are popped up on the screen if the web host is taking too long to load an action.
● In that case, check the values that are set in your server by the WordPress host and see if you can increase the benefits. Hence solving the PHP timeout error.
