Unable to connect to resource

[L3nski]

I have tried multiple different hosts to install the newt agent on. I have tried my primary network as well as vlans.

Hey,
is port 51820/udp open in your firewall in front of pangolin installation?

[L3nski]

According to the VPS yes. I have tried both in a VPS and on my local server.

A couple of things you could check: make sure the endpoint on the Newt logs and in the Gerbil section of the config.yml resolves to your VPS IP from your Newt location. Usually you can run nslookup to check.

Next make sure one more time nothing is blocking that port and you did allow UDP. UFW or iptables can block.

Finally if all that is good run a tcpdump on the VPS and filter for that port and see if you are getting packets. You can run newt to connect or see if you can connect with netcat

nslookup example.com
tcpdump -i any -n udp port 51820
nc -uv {vps_ip} 51820

Thanks all for the advise. Looks like 51820 is blocked somehow but cant find where.

[oschwartz10612]

Hum that's odd. You could look through your VPS settings maybe in the hosting provider and also check UFW and IPTABLES rules to make sure it is not blocked.

Who is your hosting provider?

iptables -L
ufw show added

VPS is RackNerd. I think that it has to do with my local firewall. I'm running PFSsense. Reason I say that is that it's not working even if I run. Pangolin locally so I feel like the Newt connection is the issue which is local in both cases. VPS iptables

Yes the port is supposed to be forwarded
