i recently changed my internet plan at the same provider. I kept my router and everything … only my external ip changed during this plan change.
But since then, i am not able to connect with my NC from outside. “This site can’t be reached - time out”. In the internal network (192.168.x.x) NC is working. I checked my dds -> it is fine (new ip), i checked my router -> every virtual lan/forwording port was kept, i made a renew on my ssl certs. In apache v-hosts is the dds domain cloud.xxx.com -> so this could also be not the problem.
I don’t know what i can check now … everything is the same, only the external (global) ip is a new one. I also can’t connect to ssh.
Thank you @gas85! It is telling me, Port 80 and 443 are closed.
But i configured/not changed the port forwarding at the router. I have now done a router reset and have again set up port forwarding, but it is still closed. It worked for years with this router setting. Could it be a issue at the server/ubuntu&apache?
But why should a new external ip affect apache?
Directly via IP over the local network with 192.168.0.x is working without problems. But with the global ip it is not working. It really seems a problem with the ports from outside but as you can see in my last answer, als ports are set correctly and so it worked for years.
