Connect to Nextcloud Box (RPi3) via Internet

my Nextcloud Box runs with Nextcloud 11.0.5 pretty well within my local network.
Unfortunately, from the Internet, I cannot connect to my Nextcloud.
I opened the ports 80 and 443 in my Router “AVM FritzBox” and entered the IP Address like this

What did I do wrong?

Thanks! Alex

Hi, I don’t know how the FritzBox does it: You need to ensure dynamic DNS name is registered ( Then the incoming connections on port 80 and 443 need to be forwarded to the right internal IP adress of the (Keywords to look for in the Fritzbox interface: “Freigabe”, ‘Permit Access’. Look online to find guides how to do the setup)

Is the hostname registered as ‘trusted domain’? See here

Hope this helps
