Bug Report: VPN no longer functions with firmware 29.83.x.x - KNERD - 04-20-2018 08:49 PM

As the title mentions, and even with 29.83.0.30 , the newest one.

The log shows no errors, and in fact nothing during boot.

I had to return to 29.82.0.20 to get VPN functioning again.

Dear Customer,

Please follow this FAQ to reproduce the issue, and make sure the issue is caught in syslog on level 6,

Please also send us the config.bin and the openvpn configuration file so we can have a look.

Thanks

I have the same problem.
VPN is broken on V83.

When on a call I have brief 3 seconds audio dropouts every 48 minutes.

This is what an excerpt from syslog on the phone whenever the audiodrop is happening:

Apparently there is a TSL soft reset happening.
This is only happening when live on a call, not when the phone is idle and causes the audio to drop on all phones I have tried it on. Never happens on V82.
