No Webadmin GUI available after update
After several attempts to solve this issue in Zentyal 6.X, the error was in a ssl_certificat.
If you encounter no webpage to administer your Zentyal server try to fix the following:
change /usr/share/zentyal/stubs/core/nginx.conf.mas, line 115 to: ssl_certificate_key <% $zentyalconfdir %>ssl/ssl.pem;
This used to state “ssl.key” rather than “ssl.pem” - with this change in place webadmin started working again. That's all.
