• 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.

Issue Clean install of Plesk gives 502 gateway errors when installing ssl certificates

peterindexed

New Pleskian
I have installed Plesk on a fresh server, this is the second try on Ubuntu 20.04LTS
Everything works until I install the SSL certificate from Lets Encrypt, then all the websites, both existing and new gives 502 bad gateway. The websites works on port 80 but not on 443. Both html and php is working on port 80.

Nothing is in the logs, actually the logs are empty, both under websites and /var/logs

If I disable nginx proxy mode SSL works

I have tried repairing, restarting services, the server
