I have two domains that I use for one of my networks. One I had tried to forward to the domain that the network is actually installed on.
When you forward a domain name to your network with masking enabled your network looks the same but nothing really works. The viewer just sees blank pages inside the network.
So I removed the masking and now just forward the domain without masking and it works great.
Hopefully, this will prevent others from thinking their network is working even with the masked domains.
