I am using an Ubuntu Machine with docker.
I don't know how to fix this problem.
The domain is used to point to the nextcloud I installed on my server. I made an A dns entry that points to 192.168.1.77. And linked it to the right port with Nginx Proxy manager. The only problem is that i can't create a SSL Certificate with Nginx Proxy Manager for this domain.
That IPv4 Address is within a Private IPv4 Address range and thus not directly accessable from the Internet; now if you have a valid non-private IPv4 Address that is NATed to that Private a IPv4 Address. Then the said valid non-private IPv4 Address is the IPv4 Address the LE can access.
