# 500 & 503 Connection Timeout errors

 * I’m at a loss and struggling with this… I keep getting lots of “503 Connection
   Timeout error” at different times during the day and don’t know how to troubleshoot
   this or get to the bottom of it… I don’t have very many plugins installed in 
   my wordpress and I do have a caching plugin (LiteSpeed)… My website (www.chaindlk.
   com) and WP backend feel very slow and sluggish but it seems that anything I 
   do (even something as simple as processing the Postie plugin queue) can trigger
   a 503 server timeout error… how can I troubleshoot this and avoid these timeout
   errors?
    Thank you

 * Thanks for that. I read it through. The problem is the article refers to a persistent
   error whereas in my case it happens every once in a while (but too over, like
   once a day or more) and then 30 min later the site is fine and I can’t trouble
   shoot that by removing plugins because I don’t know when it will happen and even
   if it happens removing plugins wouldn’t tell me if the server load just diminished
   or if it was removing the plugins that fixed it.
    There must be a way to find
   out WHICH pluging or script is causing it and how to address it, no?

 * To find a plugin or theme conflict, please attempt to disable all plugins, and
   use one of the default (Twenty*) themes. If the problem goes away, enable them
   one by one to identify the source of your troubles.
 * If you can install plugins, install and activate “Health Check”: [https://wordpress.org/plugins/health-check/](https://wordpress.org/plugins/health-check/)
   
   It will add some additional feature under create a new menu position Tools > 
   Site Health. On its troubleshooting tab, you can Enable Troubleshooting Mode.
   This will disable all plugins, switch to a standard WordPress theme (if available),
   allow you to turn your plugins on and off and switch between themes, **without
   affecting normal visitors to your site**. This allows you to test for various
   compatibility issues. There’s a more detailed description about how to use the
   Health Check plugin and its Troubleshooting Mode at [https://make.wordpress.org/support/handbook/appendix/troubleshooting-using-the-health-check/](https://make.wordpress.org/support/handbook/appendix/troubleshooting-using-the-health-check/)

 * I have done all of this.
    The problem is that I cannot replicate the 500/503 
   errors, they just happen intermittedly
