After running the command specified in the web installer and seeing "All services have been configured" in the ssh window the web-installer did not refresh (I even waited about one minute).

I refreshed the page manually and saw the code in the first attached screenshot. If I try to visit ip/froxlor then I see what's on the second screenshot.

 

After the command is finished, by default, php-fpm is used and mod_php is disabled. The corresponding php-fpm configurations for froxlor are virtual-host based, so you should open froxlor using the specified FQDN from the installation.

Ok, so in the web installer I specified kieubasa.pl (this domain is only for testing purposes) so I tried going to https://kieubasa.pl/froxlor/, but the result is the same as in the screenshot

restart apache (not reload)

 

So 'systemctl restart apache2' right? Still doesn't load correctly

 

Btw at https://kieubasa.pl/ I see the standard apache for ubuntu welcome screen. Is that correct, or should I rather see some froxlor one?

Well then it's most likely that something is misconfigured regarding IP addresses. You seem to use cloudflare for the domain. Does the target ip address match the servers ip address and the ip address you've specified in the installation? The virtual hosts are generated for specific ip addresses. So if you have e.g. a setup with a private ip address like 192.168.x.y or 10.x.y.z or whatever, you need to specify this ip in froxlor or the vhost will not match and thus display the apache default welcome page

Yes, I had to correct the IP in the web installer as it was showing the Google's internal 10.something (probably the same as the CLI-installer was providing as the URL when it finished - http://10.128.0.7/froxlor/) so it should be good.

Could You tell me how can I verify that without the access to the panel?

Check Server IP:

ip a s

Show generated virtual host config:

cat /etc/apache2/sites-enabled/10_froxlor_*.conf

And there it is:

IP Adress of the server: 10.128.0.7

Your vhost binds to: 146.148.71.223

Thus - no match - no webui

Run the following to switch your ips in froxlor:

cd /var/www/html/froxlor
bin/froxlor-cli froxlor:switch-server-ip -s 146.148.71.223,10.128.0.7

after that you might want to rebuild the vhosts (or wait for the cronjob):

bin/froxlor-cli froxlor:cron -fd

 

You meant bin/froxlor-cli?

root@instance-20240606-091317:/var/www/html/froxlor# bin/froxlor-cli froxlor:switch-server-ip -s 10.128.0.7,146.148.71.223
Switching IP 10.128.0.7 to IP 146.148.71.223
Note: 10.128.0.7 not updated to 146.148.71.223 - IP already exists in froxlor's database

*** ATTENTION *** Remember to replace IP addresses in configuration files if used anywhere.
IP addresses updated

Unfortunately, the page still didn't change

Unfortunately you blindly copy and paste without thinking. See my edited post....ips were in wrong order. Just READ the messages:

Note: 10.128.0.7 not updated to 146.148.71.223 - IP already exists in froxlor's database

And yes, of course I meant froxlor-cli

The login form now shows up correctly, but when I try to log in, the website just refreshes.

The password is correct because if I try something else then it says wrong username / password.

Clear browser cache etc. 

Thank You for your help and quick responses, the panel is now fully working.
