I’m surprised you could use 4G with DuckDNS. The carrieres are nearly all using network address translation. Who’s your carrier?
KPN, a dutch telecom provider
Ah ok. I know nothing about European carriers. All the ones (I know of) in Australia are CGNATed. It’s a pain. I can receive push messages from HA if my main connection goes down but I cant log in to see what is going on.
I was thinking of using a webhook relay service as featured here https://youtu.be/WSVX-LRP1ZI but if Remote UI works I’d rather put my money back into HA.
Indeed.
Was already contributing to HA, so this bug made the switch easy 
It might be a way around my work’s firewall too. I mostly leave my phone wifi off at work because of this.
