Using OpenBH 5.3.002 (also 5.3.001) all works fine. I can't understand what happened, but I think Nordvpn had deprecated old SSL (no access with TLS < 1.3))
There are the two logs, with different versioni of "OpenSSL"
OBH 5.3.1 and 5.3.2
OpenVPN 2.4.3 arm-oe-linux-gnueabi [SSL (OpenSSL)] [LZO] [LZ4] [EPOLL] [MH/PKTINFO] [AEAD] built on Sep 16 2021
library versions: OpenSSL 1.0.2r 26 Feb 2019, LZO 2.10
OBH 4.4
OpenVPN 2.6.3 arm-oe-linux-gnueabi [SSL (OpenSSL)] [LZO] [LZ4] [EPOLL] [MH/PKTINFO] [AEAD]
library versions: OpenSSL 3.1.0 14 Mar 2023, LZO 2.10
I'm not happy because in 5.2 and 5.3 versions lcd4linux doesn't seem to work well (the weather doesn't work) and my wife keeps looking at the forecast on the LCD display of my SOLO4K, but the functionality of VPN is much more important
Does anyone know if it is possible to upgrade the openVPN version in OBH 4.4?
