Connection to 1 particular node disconnects

Hi everyone,

I hope I’m not duplicating any other threads on here but I couldn’t find anything that relates to the issue I’m having. If there is, please point me in that direction.

I am have difficulty with my node disconnecting from one particular node. When I’ve connected to others, I have not issues. When I connect to the problem node, it will connect for about 30 seconds or so and then disconnect. At first, I thought maybe I was having some network connectivity issue between me and the remote node, however, after checking latency, jitter, etc. all of that is solid. I ran a packet sniffer on my firewall to see if the disconnect request was coming from the remote node, but it is not. I ran the console debugger on my node and sure enough, it is sending a disconnect command for that node locally:

Any ideas on why this might happening or any troubleshooting tips someone might be able to point out to me. Any guidance would be appreciated.

The first thing I would look for is perhaps a private node connection (like 1999)
that also is the same as one of your connectee’s may have.

There is now a built in loop protection.
Considering you manage to connect for 30sec, it may not be likely but still a possibility on slower systems.

You will need to look at it though.

If all checks out,
how about showing us verbose 5 output on the disconnect
asterisk -rvvvvv

So I tried removing the private node altogether to see if that was causing the issue and it still disconnects.

Sure thing Mike

I just connected to 43136 and was disconnected after about 20 sec.
So, I would say, the issue is not yours as I can tell.

Okay good to get some additional confirmation. Thanks for the help.
