• 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.

Resolved Continuity of SSL certificate when changing port used.

Zoo3

Regular Pleskian
I'm using Let's Encrypt on Plesk.

In normal access, I can connect HTTPS.
The executing program requests a different port of the site. I get an error when trying HTTPS connection to this program.

https://SAMPLE.com --> OK
https://SAMPLE.com:XXXX --> NG

By Firefox:
SSL received a record that exceeded the maximum permissible length. Error Code: SSL_ERROR_RX_RECORD_TOO_LONG

This is because the program does not take over the certificate well. How can I activate Let's Encrypt's certificate when the ports are different?

Please help.
Best Regards,
