Issue with DDNS

i don’t know if this is the ideal place to aks but here we go…

I tried to make my Nextcloud accessible from the outside using DDNS

following this Tutorial Steps:

I have seen many similar Tutorials,

but not a single one works for me.

I always get an ERR_CONNECTION_RESET Error.

I tried disabling the firewall of my device, but this did not help.

Others suggested changing the IP Address to my Server’s one,

but this did only work in the internal Network.

When I ping my URL i get a normal response.

I would be glad for any help :slight_smile:
