Changed hostname, now i can SEE folders/files, but can not access them

🚧 Installation
1

So I had a working NC11 install with DynDNS through NoIP, but changed my dyndns service (from no-ip to Afraid.com) to use a domain name I already had. Everything seems to point back to the server (even my wiki that i installed in a completely different folder works ok). I got new ssl certs for the new domain name…again, works ok with wiki, and with NC11…I can log in and navigate through all the directories (user and admin) on a secure connection, but when I try to access a file (to view or download, or upload new files), I get “Unknown error 503”. Because other sites on the server seem to work ok, it seems to be limited to just NC11. I also made sure that www-data:www-data had ownership of the data storage folder (though that had not changed).
So, not sure what I did (or didn’t) do, but I need some assistance, please.

Server is Ubuntu 16.04
Apache2
Maria DB

Thanks for any help you can provide.

Can you check the Apache log file and provide the section of the error? Make sure to check both the access and error logs.

not sure exactly what to look for, but here is the output of tail /var/log/apache2/error.log

Does this help?

Best practice is to have separate logs for each VirtualHost, I assume this log is specific for NC.

From what I can see it has problems finding the files status.php and index.php in the folder /var/www/html. Is this the folder in which NC is installed? If not it could be that your VirtualHost config is not correct.

5

ok, it may be the vhost then. would that prevent only NC from working properly…while others still ok?

6

It can do yes since each vhost have their own configuration settings.

As from the error file it shows it is trying to access the files in /var/www/html. If this isn’t the RootDocument folder of NC it would mean for some reason a different vhost is processing the request, so would need to find out why it would switch vhost. This could be for some reason the URL is incorrect.

7

Ok, I looked the vhosts…all have the NC document root at /var/www/nextcloud (same as the initial install). not sure why it was looking it in …/html . but that has not changed anything regarding access. :disappointed:
What else can I try?

(or is it time to “cut bait”, reinstall NC, and point it to the existing data directory?)

if anyone can help me interpret these errors:
