Very strange issue after last firmware upgrade

[iz1dsj]

Hello,
I'm running remoterig between 2 sites, using Mikrotik Routerboards, estabilished a PPTP VPN connection between the two, remoterigs are talking to each other inside the VPN, after last firmware upgrade sometimes the control head gets stuck, red led on the AUX/MIC, 10-30 seconds and it comes up.
VPN looks stable, the strange thing is that Control head rrc is not even answering to the ping from the local network like it's dead or rebooting.
It might do that for many times in one hour and then run for the whole afternoon, unfortunately lost a lot of QSOs.....
Any suggestion?
Thanks, Jack,

You upgraded from which version? And to version 2.86 I assume?

Hello, I upgraded to 2.86 from 2.85.

It surely isn't an expected behavior from upgrading. Have you checked the status page to see if it actually has rebooted?

Hello,
tonight I will start a deeper investigation, my post was just to check If you did not have this issue also on other systems, at least I'm more
sure that it might be coming from network settings.
Thanks, Jack

Hello,
we made some checks on the configuration, VPN seems to be ok but almost every time I need to turn on the radio
it gets stuck in the HELLO display. I need to remove the control panel cable and connect it back, sometimes it starts correctly otherwise I need to reboot the remoterig.
Here is the diagnostic of control panel unit:

Any suggestion?
Thanks, Jack.

It looks like some kind of network error since the status is:

RTP/UDP audio status   Stalled(40)

which means it is unable to stream audio.

You could also take a look at the other RRC's status at the same time as it could be different.

Hello,
I tried to summarize what happens in the pdf document attached where radio and control remoterig status pages are reported. At the actual state to have the radio working I need to remove the front panel cable after push button is pressed and plug it back.
Thanks for any useful suggestion, Jack.

Hi Jack,

I experience starting issues similar to yours unless I put my control RRC into the DMZ of my router (control site).

Interesting! Could be a timing issue then I suppose.

So in the PDF log you did not remove the front panel cable? Still, in step 3 it seems both RRCs have a normal connection status, which means it should work from their point of view.

[iz1dsj]

Exactly, front panel cable needs to be removed and plugged back after step 3 if I want to have some QSO...
I wanted to follow the normal steps to turn on the radio, so I power the routerboard which comes up with the VPN, then the Remoterig on the Control side, then I press the ON button.
I'm not saying that my problem is so urgent to be solved, I'm perfectly satisfied with remoterig, living between the mountains  is not easy to catch DX even in CW which is my only mode, after I built my remote site I have many new countries in my log, but since it looks like somebody else had the same issue you might find the time to debug one day.
By the way the VPN is a L2TP between two sites operated with Mikrotik Rouerboards, ping between the two networks is between 40-70msec.
TS-480 was upgraded to last firmware.
Thanks in advance, regards.
