CGNAT ISP wont allow port forwarding

Describe your issue

I moved to a new house and my new ISP is a CGNAT that wont allow any port forwarding at all (although the router allows for configuring port forwarding, it just wont work). What can I do? I dont want to lose my server and this is the only ISP available where I live. It does have IPv6, in case that helps. thanks!
