Hi Pangolin Team!

First of all, awesome project, I really love the whole app, and the documentation :)

I'm currently trying to set up Pangolin to expose my self-hosted services, but really struggling, and don't know what I'm doing wrong :(

I successfully installed Pangolin on an Oracle Free Tier VPS server running Ubuntu. I opened all the required ports 80/TCP, 443/TCP, 51820/UDP, and Pangolin seems to be running correctly.

To confirm this, here is a netcat result from my remote site:

balint@truenas:~$ nc -vzu pangolin.mydomain.com 51820
Connection to pangolin.mydomain.com (xxx.xxx.xxx.xxx) 51820 port [udp/*] succeeded!
balint@truenas:~$ nc -vz pangolin.mydomain.com 80
Connection to pangolin.mydomain.com (xxx.xxx.xxx.xxx) 80 port [tcp/http] succeeded!
balint@truenas:~$ nc -vz pangolin.mydomain.com 443
Connection to pangolin.mydomain.com (xxx.xxx.xxx.xxx) 443 port [tcp/https] succeeded!

Also, I enabled ICMP on Oracle's Firewall, as I remember correctly that it is also needed for Pangolin to work. So I can also ping the Oracle VPS as expected.

But when I try to run newt on my remote site (truenas), I get this error:

[...]

Also, I'm running Tailscale alongside on this setup, but I don't think that should interfere.

Thanks in advance for any guidance or directions I could take to resolve this issue
