Nextcloud does not display in full-featured browser

liz · April 17, 2020, 11:37pm

I upgraded from Nextcloud 17 to 18.0.3.
I am unable to access Nextcloud in my usual browser

Internal Server Error

The server log does not give any details at all.

I tried Firefox, Brave and Opera, all have the same result. I reinstalled a complete OS to remove all cached browser data and still have the same result (except that the Request ID changes)
Then I installed surf as a browser and am able to log in and view the Nextcloud instance (partially, needs css info)
All the other features of my Nextcloud work, the desktop and Android apps, but I sorely miss the calendar in the browser window.

nothing significantly different in that log for the browser which displays Nextcloud
In my limited understanding, Nextcloud is working fine, but there is some incompatibility with the browser setup.
Any hints are most welcome, thankyou all in advance.

Nemskiller · April 17, 2020, 11:55pm

Apache access log won’t give you hints.
Apache error.log can give you advises.
Look also the nextcloud.log normally at the root of your Nextcloud data folder.

nextcloud.log excerpt is at https://pastebin.com/6ktnwF15
starting from an attempted access of nextcloud

Nemskiller · April 18, 2020, 4:28am

The upgrade process maybe didn’t finished well.
Log into your server in ssh and do :
sudo -u www-data php -f /var/www/nextcloud/occ upgrade

If your nextcloud installation is at /var/www/nextcloud

Tell me the output of this command.

liz · April 18, 2020, 5:38am

thanks for your help
I get
“Nextcloud is already latest version”

I had considered a downgrade and a retry at the upgrade.

JimmyKater · April 18, 2020, 7:34am

first i’d try occ maintenance:repair (doublecheck manual for correct usage)…

liz · April 18, 2020, 10:06am

Certainly. The bash history shows that has been done 5 times in all since the upgrade.
Let’s run again

well … sigh

have you tried different browsers?
which browser do you use? at which version?

liz · April 18, 2020, 11:21am

Indeed I have used different browsers Firefox, Brave, Opera, and the only success story, Surf.
On this machine Mozilla Firefox 68.7.0esr and Brave-browser Version 1.7.92 Chromium: 80.0.3987.163 (Official Build) (64-bit)
I also tried Opera, but I have removed that now.
I’m not sure of the Surf version, that’s another machine. the interesting point is that the minimalist browser is more successful than the full-featured, and that’s how I chose the heading.

JimmyKater · April 18, 2020, 11:26am

this other machine… is it withion your lan or outside? could you try a different browser on this one?

btw: your thread is perfect as for needed infos.

liz · April 18, 2020, 9:38pm

Both are within the lan. I haven’t tried from outside.
I did also forget that DuckDuckGo browser on Android also worked.
On the laptop I tried Firefox and Opera, and did a full reinstall to remove all cached settings, to try another option.
