Troubleshooting tunnel that stopped connecting.

I am troubleshooting a tunnel that worked previously but has stopped after updating nightly build. (I think...)
MikroTik hAP is the tunnel server and the client I am using is a Microuter dongle style router w AREDN firmware- all are latest nightly 1181-xxx.

When I telnet from outside my network in to port 5525 I see:
VTUN server ver 3.X 10/30/2019

Is this correct? I do not see "waiting for connection" for example. Port forwarding seems to be working.

How can I troubleshoot further? I considered uninstalling/reinstalling the VTUN server.

Thanks- 
Clifford

Same response from working tunnel server

I get the same kind of response here when I telnet over 5525 to a node running the last stable release: "VTUN server ver 3.X 03/22/2019" followed by a NL and what looks like a couple of tabs;  I do not get "waiting for connection" or any other prompt/data. I suspect that the date in that response is likely the firmware release date and the "ver 3" is related to the firmware top level version number. My tunnel is running fine (or, at least until I wrote this).

HTH,

Thanks Don that is helpful. Something else going on with my tunnel then I suppose. Appreciate your help.

If you can see the VTUN 3.X

If you can see the VTUN 3.X message from outside your network, then, that says that you have your port forwarding setup properly.
Only two other things to check:

the tunnel client's password must match
the tunnel client's node name must match (and not be too long).

What is the node name of the client trying to connect to your server?

So I upgraded all my nodes to nightly 1190 and the tunnels work fine. Not really sure what the problem was but I learned a few things in the process. Thanks to all for the assistance. Also- I have capacity for tunnels to my station here in Palm Springs. If anyone needs one just give me a shout.

FYI, the ver 3.X is the version string from the VTUN package.   Has nothing to do with AREDN version numbers....
