Nextcloud returns Internal Server Error

ncp
nc14
#1

Since yesterday my NCP is no longer working. The sync client says

Error downloading – server replied: Internal Server Error

Going to the webpage just returns an empty page without any information.

It is not an update issue since the NCP was already updated a while ago and was working.

Anyone know what may be wrong?

Thanks in advance

You need to check your logfiles (/var/log/(apache)). Usually, the server gives you more details on what might be wrong.

Thank you for your response.

I have looked into the apache log and it seems there is an issue with the certificate

The NC error log is too big to paste here, but it contains mostly the same error anyways.

Just after rebooting, I got this error:
[Mon Oct 29 13:40:08.074234 2018] [ssl:warn] [pid 633:tid 1995570448] AH01909: localhost:443:0 server certificate does NOT include an ID which matches the server name

I did not change the certificate so I don’t know why this is suddenly supposed to be a problem now.

As for the nc-error I have no idea what is going on there, I would greatly appreciate any help.

Hi!

I ran into the same problem when updating from NC 15 to 16.
How did you resolve the problem?
