504 scan error

Hi Cory,

I am experiencing a scan error using Duplicator:

Server Status: 504 -error
Error Message:
Gateway Timeout
The gateway did not receive a timely response from the upstream server or application.

I have followed all the options as suggested at this link:

https://snapcreek.com/duplicator/docs/faqs-tech/#faq-package-025-q

and I have tested with all plugins off.

If you have any suggestions, much appreciated.

The following is a transcript of my support chat with Site Ground:

Stephen Vaughan: Hi,

I have been trying to do a backup of my site using the Duplicator plugin. I keep running into a scan error:

Server Status: 504 -error
Error Message:
Gateway Timeout
The gateway did not receive a timely response from the upstream server or application.

Following instructions given by both SiteGround support and the plugin author I have paused Cloudflare. I am still getting the same error.

I have also tried some of the other troubleshooting checks as per this documentation from the plugin developer.

Stephen Vaughan: This question is related to account:vaughanprint.com
Ivaylo Iv.: Hello Stephen !
Ivaylo Iv.: Welcome to SiteGround Hosting Services!
Stephen Vaughan: Hi
Ivaylo Iv.: Allow me a few moments to further investigate
Ivaylo Iv.: Thank you for your patience ! Would you please give it a try now ?
Stephen Vaughan: Ok, Bear with me.
Ivaylo Iv.: Absolutely, take your time ! I’ve uplifted the server limits, so hopefully this should do the trick.
Stephen Vaughan: Unfortunately I am getting the same error.
Ivaylo Iv.: Just checked the documentation and used their suggested code, may I ask you for another test ? Thank you !
Stephen Vaughan: Ok, just running it now.
Ivaylo Iv.: Absolutely, no problem. I added you this code:
SetEnvIf Request_URI “admin-ajax” DynamicTimeout=600
Ivaylo Iv.: As the reported Timeout is indeed related to the wp-admin ajax
Stephen Vaughan: Ok. If that is Option 1 from the documentation I tried it already with the timeout set to 240 and it didn’t work. Now it is reporting: 500 – Internal Server Error This is a temporary server error. Please try to reload the webpage later. If you are the webmaster of this site please log in to Cpanel and check the Error Logs. You will find the exact reason for this error there. Common reasons for this error are: Incorrect file/directory permissions: Above 755. In order files to be processed by the webserver, their permissions have to be equal or below 755. You can update file permissions with a FTP client or through cPanel’s File Manager. Incorrect Apache directives inside .htaccess file. Make sure you have not specified unsupported directives inside the local .htaccess file. Such include PHP settings and Apache module settings.
Ivaylo Iv.: Just fixed permissions as the first probable cause of the error, secondly is it okay if I backup your current .htaccess
Ivaylo Iv.: Then create a new one and add you the default WP code + the timeout code ?
Ivaylo Iv.: So we can test it this way
Stephen Vaughan: Ok. let’s do that
Ivaylo Iv.: Perfect, all set now. Perhaps are you able to clear your cache, log off from WordPress and then initiate the duplicator plugin once you’re logged in, thank you !
Stephen Vaughan: OK. Doing that now
Ivaylo Iv.: Thank you, Stephen
Stephen Vaughan: Same error again
Ivaylo Iv.: Hm, that’s interesting, indeed. Although it’s a third party plugin, a lot of clients have used it. The cause of this error could come from multiple sources starting from the plugins and going all the way to server limits.
Ivaylo Iv.: There are a few other plugins as an alternative you can use.
Ivaylo Iv.: Also you can download a Full Website Copy from the SiteGround from the cPanel -> cPanel Backup -> Download A full website Backup
Stephen Vaughan: Ok. I might write to the plugin vendor to see if they have any suggestions and I will try the cPanel solution.
Stephen Vaughan: Can you describe a bit more what you mean by:
Stephen Vaughan: The cause of this error could come from multiple sources starting from the plugins and going all the way to server limits.
Ivaylo Iv.: Sometimes a plugin is to compatible with another plugin, so in this case, this can be the cause of the error. In some cases, due to its nature – WordPress plugin will take a lot of server resources as the script behind it is not properly optimized.
Stephen Vaughan: OK. I will go off and do a bit more troubleshooting on this.
Stephen Vaughan: Thanks for your help.
Ivaylo Iv.: You’re most welcome, Stephen !
Ivaylo Iv.: Please, if anything else comes up feel free to reach us back anytime !
Ivaylo Iv.: Best wishes, and have a peaceful evening!
