Hi,

Maybe your server Nextcloud dosen’t have a server DNS register.

Can you try this in your server :

nslookup wikipedia.com

or nslookup other domaine.

You have a reply?

If server not resolve domaine name, try add a server dns (etc/network/interface?) and try to connect whit your browser ‘yournextcloud.tdl’.

I haved a long time reply whit my browser in nextcloud beacause my server dns no response… bref… My english bad :rofl:

I cannot see why it could be a domain issue. I serve other website (gitea) on the same domain and it works super fast.

Are you by chance using Nextcloud Office?

Yes I am. I mean it is installed among with collabora built-in server:

core-common.js
talk-files-sidebar.js

Everything is cached except of those two files? Why are they being downloaded on every click?

Maybe also for an experiment try to temporarily disable the collabora CODE and see if it makes a difference, this app has shown to cause performance problems on other instances

I don’t think it is a problem (tried to disable office, same issue).

In my opinion those two js files are causing the issue. You can try to reproduce the same slowness if you switch the browser into throttling mode. See screen bellow:

So on every page hit it downloads those files. For the LTE 15mb is a lot.

I don’t have dashboard enabled, so not exactly the same.
Reloading “Files” app loads the core-common.js as well but in may case it is cached (like everything else). I don’t see any difference for 3G/4G throttling (I think because of caching).

Solution :star: :star: :star: :star: :star:

Ok. I think I have found the root of the problem. And it is not related to the server at all. I am using LibreWolf as my browser. So because it has very strict security policy and low memory usage, it does not cache files larger than 50kb.

I went to its settings about:config and filtered variables browser.cache and found it out.
After I changed those settings, those LARGE js files started being cached, and the web site works smoothly now.

Thanks everyone for any help and support. :fist:
