Nextcloud version 13:
Operating system and version Debian 9:
Apache or nginx version nginx 1.10.3:
PHP version 7.0:

Hello all,

I am in the process of transferring my old nextcloud instance to a brand new server.

I have restore with success the /var/www/nextcloud folder, the data folder and the mariaDB dumb.

I have setup a similar nginx server, I thought all will be ok, bu then I try to access to my instance, I have this 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.

When I check the error log of nginx, I have this error when I try to access the nextcloud instance:

It seems to be a problem with some permissions, whereas I think they are ok:

srw-rw---- 1 nextcloud www-data 0 May 28 22:29 /var/run/nextcloud.sock

Is there something I am missing ?

Thanks in advance !

As far as I can see the errror-log says:
stat failed for /root/cloud/nextcloud.log
so
srw-rw---- 1 nextcloud www-data 0 May 28 22:29 /var/run/nextcloud.sock
is irrellevant.

Moreover you shouldn’t put application data in the /root directory, never.

Thank you for your answer,

You are right, I have moved it to another directory.

The permission where wrong in the data directory. I have fixed it. I still have a Internal server error but now nothing appears on the nginx or the php logs.

However I have this in the nextcloud.log

Did you install the php-module for apcu? It looks like you didn’t:
“Is the matching PHP module installed and enabled?”
