• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Web preview - 403 Forbidden Nginx

Many different reasons can be here. It's really difficult to say what is wrong there without logs. Try to repair vhosts permissions at least with

# plesk repair fs
 
Hello, thanks for your answer !

I just tried and it didnt worked.
Checking virtual hosts' file system ................................. [OK]
Error messages: 0; Warnings: 0; Errors resolved: 0

Do you have an idea where I could find the related error in the logs ?
I tried to look for it in the logs of the different vhosts, and in /var/log/nginx but didnt found anything related to it.
 
Hello,
I tried to contact Plesk Support Team but wasnt able to because I purchased my license from a reseller.
I contacted my reseller and they have not been able to help me.

But the good news is that I finally found how to solve the problem by myself.
I had to add the IP of my server in the file located there : /etc/sw-cp-server/conf.d/trusted_ips.inc
