VU+ and openvpn ok on stretch?

Hi guys
I am using openvpn (no script) to connect to my VU+ box. I am holding to update to the latest stretch and get some more info.
Can somebody confirm that is working?
Otherwise, in case is not working, can I reinstall the older osmc?

Don’t see why it would be a problem.

Unfortunately it doesn’t work good anymore, I suspect it is from the sever side running on VU. The VU box had also a major update, I can’t say exactly where the problem came from.
Vero connects to the VU, gets even the EPG and picons loaded, but the video signal is very bad, looks like watching TV on a stormy day, lots of greenish colored squares and click noises.
Maybe an MTU issue? Is there maybe a way to check the packets drop?
