# Error 503 while performing scan

 * Hi,
 * I’m receiving a 503 error while performing scan with your plugin. It stops in
   the 4th item, and so after a while, displays the above mentioned error.
 * My host said me the following, after verify the issue for me:
 * “We investigated your case and found that the reported issue is from the plugin
   end as from server end we checked everything seems fine. 503 service unavailable
   error comes indicating that server is still functioning properly but the process
   that opted to return the 503 response code. I would recommend you to escalate
   this to your plugin author to see why it is throwing this error If incase it 
   points to any server settings we can gladly check that for you and there can 
   be multiple factors for it and plugin author can better analyze it for you. ”
 * Can you please help me?
 * P.S. my server is running PHP 7.3 and my wordpress is 5.2.2.

 * Hi [@marcoszy](https://wordpress.org/support/users/marcoszy/). I’ve reported 
   this error to the development team working on an update to this plugin.
 * In the mean time, have you tried running the plugin from a local copy of the 
   site? This would help get around any server-side issues (assuming that’s what
   this is), and it’s preferred to run the “linting” this plugin does in a non-production
   environment.
 * Thanks for the feedback!

 * I’m also having this issue. However, in my case… immediately following the 503,
   my site is basically dead. All subsequent access returns 503 and I have to restart
   apache to continue.
 * I’m running plugin 1.5 on WP 5.3.2 with PHP 5.6.40.
 * If I disable all of my plugins except the compatibility checker, the scan works
   fine… but that sort of defeats the point.
