Devolutions Gateway on Linux

After spending the better part of today trying to get my gateway to work... I will now ask for help...

Devolutions Gateway is running on Linux Ubuntu 26.04. TLS Cert from Let's Encrypt.

He says he is happy... See attachments.





Devolutions Cloud... says "Unreachable Gateway". I have confirmed 7171/8181 are indeed reachable from the internet and local LAN.

Each time I get "Unreachable Gateway" error, this is the log entry on the gateway:
(My network is a /23... .255 is okay in this case)

I hope someone has gone through this before and can just give me a magic solution ;)

Or... just point me in the right direction... this works too
