ISP put me behind NAT (lemmy.world)

I'm connected via a 4G modem. Got this setup about 3 years ago. In the beginning it was enough to look for the public IP (what's my IP). The modem showed some sort of private ip in the ui. I'm running stuff at home (Homeassistant, Gitea,) and bought a domain and pointed it to my home IP via Cloudflare. After some time I've noticed my modem shows the public IP also internally. For about 2 years now it ran flawlessly, the IP changed from time to time, but not really more than once in several weeks. For about a week all stopped working and the modem shows IP 100.xxxx and outside 85.something I guess I'm behind NAT now. Normal port forwarding on the modem is useless now. Is it possible to open the ports via UPNP? I've tried via miniupnp from my Ubuntu server, but it just throws an error.

upnpc -a ifconfig enp1s0| grep "inet addr" | cut -d : -f 2 | cut -d " " -f 1 22 22 TCP

Can I use this to somehow open the ports via UPNP on my modem and bypass the blocking? I can't even OpenVPN to my modem anymore.

EDIT: i also run AdguardHome, that I use as Private DNS on my Android phone

UPDATE: everything except Adguard Home used as Private DND on my Android works! I've used this: https://github.com/mochman/Bypass_CGNAT/wiki/Oracle-Cloud-(Automatic-Installer-Script) - free Oracle VPS + automated well described script. Even HTTPS works fine!

i've been on CGNAT and just pointed my domain to my ipv6 address with no issues - every isp should hand out huge v6 subnets dedicated to you.

Since my v6 prefix is not stable, i use ddclient from my homeserver to update my domains AAAA record

wdym except Verizon? I have a whole section of /56 for me in ipv6, tho the Verizon website is ipv4 only

Verizon IPv6 rollout technically started but has been very limited in the last few years. I live outside one of the biggest cities in the U.S. and it hasn’t even made it here yet. In the last five years they’ve only made it to 50% of their userbase being capable.
