may be some one can help me
i did a fresh install of nextcloud via snap on ubuntu 18.04 server
everything worked fine during installation and inside my lan but from outside lan i cant any access
portforwarding is set and dyndns is working well
i got some servers running with egroupware, websites, ftp and so on
they are all present from outside
i have set the trusted domains without success
i think there is a problem with ubuntu because ssh is also not working from outside lan
do you know how to open the server?
