Nextcloud pi Internal error

Hello, i have a problem, when i am trying to connect to my nextcloud there is a message "
Internal Server Error

The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log. "

I’m using no-ip as a DNS. If someone can help me,
(sorry for my english it is not my native language).

Hi Enzo,

is it a new installation (and you’re trying to do your first login) / has it been upgraded / you did nothing and you’re having this error with no clear motivation?
Did you check the server logs?

Cheers,
Marco

No, it’s not a new installation, and nothing in logs (nothing wrong I think), I didn’t upgraded anything. Thank you for your answer

An error 500 (Internal server error) should generate something at least in nextcloud.log (it’s in json format, usually in the nextcloud data folder).
It’s hard to tell what the cause can be without any log message.

Regards,
Marco
