security issue with openvpn???

[camelator]

I was not able to connect with wireguard. The command line is looping itself.
so I tried with openvpn. It looks better but with issues:
note: I successfully ran the GUI connection tool with success.
I am using Ubuntu 22.04
The single difference is I have to use UDP port 123 to avoid blocking port on my internet box (it works with the GUI connection tool)
I also have the same error on my ARM box: (nanopim4v2)
here is what I've done:

change in file connect_to_openvpn_with_token.sh the UDP port to 123

then I ran:

sudo VPN_PROTOCOL=openvpn
DISABLE_IPV6=yes
DIP_TOKEN=no AUTOCONNECT=true
PIA_PF=false PIA_DNS=true
PIA_USER=myuseraccount
PIA_PASS=mypassword
./run_setup.sh

and here are the error log I have:

sudo cat /opt/piavpn-manual/debug_info

2023-01-07 12:58:11 DEPRECATED OPTION: --cipher set to 'aes-128-cbc' but missing in --data-ciphers (AES-256-GCM:AES-128-GCM). Future OpenVPN version will ignore --cipher for cipher negotiations. Add 'aes-128-cbc' to --data-ciphers or change --cipher 'aes-128-cbc' to --data-ciphers-fallback 'aes-128-cbc' to silence this warning.
