Switched ISP and can't access HA externally

I just changed my ISP and use duckdns, a reverse proxy and synology. The duckdns ip automaticaly updated and looks good on the synology. Not sure what else to check. Let’s encrypt issue?

** FORGET IT. WIPED MY ROUTER AND HAD TO SETUP THE PORT FORWARDING RULES AGAIN. ALL GOOD **

I know you solved this, but I want to mention that it’s becoming increasingly popular for ISP to run CGNAT.

In this set up, there is no inbound port access to your router through your Public IP address.

Might help if someone reads this and someone else moves ISP but can’t access HA :slight_smile:

Mobile ISP’s love it due to ipv4 exhaustion… why cant the world embrace ipv6?? lol.

some isps who use cgnat are nice enough to allow port forwarding… just tell them its for cctv. another workaround would be zerotier one… brilliant work from those guys! or even ngrok!
