Bad Server Response

[grupoboheme]

Hello I need help, my EspoCRM stopped working, now I can't login and all I get is a "Bad Server Response" error message, first I thought it was the PHP version so I asked my provider to downgrade it to 7.3 but still same error, please any one? Help of ideas?

This is my domain: https://www.grupoboheme.com/espo/

And error log

Hello,

Do you know of any notable changes made to the server (like a software upgrade) that may have triggered the issue? What version of EspoCRM are you using? How is the server configured?

Based on the error log and your PHP version, I'd guess that you may have an outdated version of EspoCRM running, which may be contributing to the issue. It looks like the "Bad Server Response" is given because API requests are not routed to the correct endpoint and EspoCRM is trying to respond to them with a web page. That may be an issue with the configuration of your HTTP server.

Have you manage to fix it?
If you're using the newest version of EspoCRM, only 8.2-8.4 versions of PHP are supported based on official readme:
