Internal Server Error after Accessing Wiki

Hello Friends!!!

Has anyone ever experienced the error message: “Internal Server Error” after accessing the Wiki Page and then pressing back button on the browser, sometimes it’s getting Internal Server Error Message.

After getting Internal Server Error Message and trying to access the ERPNext site using URL Domain, the Cloudflare Status Message says “502 : Bad Gateway” it keeps error for 10 minutes and then the URL can be accessed after 10 minutes later.

The thing is, the ERPNext works well when I access it using Local IP Address.

Notes : The ERPNext site runs behind NGINX Proxy Manager and Cloudflare.

Any Solutions?

Thanks In Advance!
Regards
