• 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 Extensions of Plesk Obsidian: internal server error

Hans Lunsing

New Pleskian
I use Plesk 18.0.20 (obsidian) on CentOS 7.7.

When i go to the extensions catalog page (/modules/catalog/index.php/catalog/featured) on one of our servers I get an "Internal server error". My extensions (/modules/catalog/index.php/installed) do show up, but for every one of them an error line "[2019-10-30 13:14:16.615] ERR [extension/catalog]" is added to the panel log file (/var/log/plesk/panel.log).

When on the update page (/modules/catalog/index.php/updates) I try to check for updates I get an error "GraphQL error: Internal server error" in a small pop-up window.

I don't know if it is related, but updating the Let's Encrypt extension fails with an error message:
-----------
Error: Nie udało się zainstalować lub zaktualizować rozszerzenia 'Let's Encrypt' (pakiet: letsencrypt):
[2019-10-30 13:34:15.657] ERR [panel] Error in cURL request:
[2019-10-30 13:34:15.675] ERR [panel] Error in cURL request:
Error in cURL request:
-----------
The error message is in Polish although my system language is Dutch. Google Translate says it means:
"Failed to install or update the extension 'Let's Encrypt' (package: letsencrypt)."

Updating Plesk itself and the other extensions succeeds without problems.

Can someone point me in the right direction for a solution of these problems?
Many thanks in advance!
