My Raspberry Pi today got disconnected from newt to my pangolin. Then, I researched and found out that newt latest version could be causing issues so, after that I updated my pangolin to latest and while using newt latest still getting the problem.

My other server with old newt I installed a month ago is working fine though, before and after update. But this newt was installed recently this week

On Pangolin dashboard, it shows 1.3.4 as version. But never connects

Here are newt logs.

Extra Information (Don't know if its relevant) -
First of all I'm not sure why these errors started, because it could be because of my firewall of OpenWRT which I installed recently, because I'm new to that. My Broadband IP Address also changed recently due to dynamic ip and its possible that in past I would've set some settings that blocks access from my server to my IP due to change, could be cloudflare proxy, could be my cloud vps firewall rules. I will be checking later this afternoon.

Oh my god, I'm so sorry! It was indeed my Cloud VPS Firewall Ingress Rule. I changed it to XXX.XXX.XXX.0/24

I found that on https://ipinfo.io/what-is-my-ip

Now, its connecting properly :)
