Thank you very much in advance for any help.

Hey @messaid welcome to the Nextcloud community :waving_hand:

You started a topic in support category. Unfortunately you ignored the template and a lot of information to help you is missing. Please edit your original post and add all required details like Nextcloud version, webserver type and version, os version, related log file content. Use the support template.

Without additional information the community members cannot help you.

Hi @scubemuc

I added information according to the template as you suggest.

are you sure about that version? assuming the version you’ve quoted is the version installed… that is no longer supported and EOL.

that cant be true either… could it?

Very old, your server OS and Nextcloud. Is it possible, that certificates are outdated now (including CA certificate), that decryption is not possible anymore?

btw.:

We recommend, to upgrade to Ubuntu 24.04, PHP 8.3 and Nextcloud 30
