UI of Nextcloud not available

Currently not being able to load the Nextcloud user interface.

Run on local network (with NUC intel).

Error message in the browser: DNS address could not be found. Diagnosing the problem.

DNS_PROBE_POSSIBLE

See screenshot for log output

Any help is much appreciated

Your browser on your PC not being able to reach your server won’t be reflected on your server’s logs.

If you have an issue with Linux Mint, you’ll have to fix it on Linux Mint.

Within our guides that show you how to trust the Root CA on Linux there are a couple of warnings related to using flatpak apps. You should probably check that you saw those first, if you’ve taken that into account, I can suggest a couple of other things.

Thank you for your reply.

I have followed the instructions for connecting with Firefox on Linux mint with downloading the root ca.

Perhaps the change of ip-adres has effect on this as well?

I will go through the proces again and report next week, since time is scarce this week.
