Hello everyone!
Device CCR1016-12G.
Updated from 6.49, everything went great. I hoped that openvpn would work on udp, but it did not work.
The connection is established, Mikrotik receives the address, but the packets do not go. And most importantly, while the ovpn interface freezes. It cannot be deleted or edited. Only reboot helps.
I tried to put MTU 1400, it did not help either.
By tcp it works fine, but not satisfied with the speed. Above 30M does not rise.
