Hi.
After “try” to change domain, , it’s impossible to access nextcloud, also on localhost.

There’s a nextcloud screen on the browser with a error code.
The erros are like the below, tryed to returd at initial condition / domain, but nothing change…

Other errors, seems that Nexcloud can’t find files, but I don’t know why…

Hi,
Did you change the ‘trusted_domains’ parameter in config.php after changing domain?

4

Yes, i’ve changed config.php , nextcloud.conf, and request a new certificate.

After the problem i’ve tried to go back with previous domain (and previous certificate), but the problem is not resolved.

The actual section of config is

'trusted_domains' => 

  array (

    0 => 'localhost',

    1 => 'MY-DOMAIN', 

  ),
5

(partially) Solved deleting config.php
Then a new login (with new admin user) by the webborwser interface, tested also with the new domain.
Some problems with the cerificate and some user access…
