Zentyal backend and unable to connect to localhost:8443

[rpennol]

Ciao to all !
I've a big problem with a Zentyal 7.0 server
I'm trying to connect to backend and i have the error message "An error occurred during a connection to localhost:8443".
Any ideas ?

You must analyze the following log files in order to see why you are getting that error:

* /var/log/zentyal/zentyal.log
* /var/log/zentyal/error.log
* /var/log/nginx/error.log
* /var/log/syslog

Also, you can check the status of the following services:

Code: [Select]

sudo systemctl status zentyal.webadmin-nginx zentyal.webadmin-uwsgi
sudo journalctl --no-pager -u zentyal.webadmin-nginx

Moreover, you can see if the port is listening:

Code: [Select]

sudo ss -tunpl | grep ':8443'

Finally, in case the services are running and the port is listening, make sure the firewall is not blocking the connection. You can stop it temporarily with the below command so you can adjust the rules.

Code: [Select]

sudo zs firewall stop

Hmm, both services are up and running and the port is listening, so the module seems to be working as expected. Did you try to connect from another machine?
