So, I'm getting back to you. The VPN works fine in my country, but I haven't tried it in others, and none of them would connect to the stream. I tried a few channels, disabling AFR (Automatic Frequency Response) made it seem pretty smooth. The key test was on popular sporting events. Another surprising thing is that I couldn't get the Z11 Pro to use a static connection. I tried everything, but no luck. My only solution was to add a static DHCP lease in my router's settings. Thanks, Lucky, for your help.
Edit:I'll try all the settings you recommended for NordVPN anyway, thanks a lot for your help
I made a mistake, it's Proton VPN I have, not NordVPN.
I can't find this option
Turn postquantum encryption OFF!
If the option insn't there it can't be setup.
Sport events are often blocked by isp. Saw it on new website.
You can set static ip.
No problem.
Write down your ip you have now.
Do you know your modem ip?
Via android phone youn can hold wifi button in for 2 sec.
Then details and then cogwheel.
Then youb see admin router and then you see your router ip.
It very f*cked *p that teamviewer doesn't work on the boxes yet.
Then i could set it uo for you.
But teamviewer didn't fixed it not yet.
Since z11 still not.
