OVNP Connection reset, restarting [0] - Client stays on Connecting

RouterOS Beginner Basics
1

Hello everyone,

Strange policy for new comers you have here. Straight to the topic, as this is the 2nd time I am posting the same information.
I am trying to configure the VPN of RB962UiGS-5HacT2HnT w/ RouterOS v6.45.7.

Below is the CLIENT.OVPN file:

client
dev tun
proto tcp-client
remote WAN_IP 1194
resolv-retry infinite
nobind
persist-key
persist-tun
;mute-replay-warnings
ca ca.crt
cert client.crt
key client.key
tls-client
remote-cert-tls server
cipher AES-256-CBC
;comp-lzo
verb 5
;mute 20
auth SHA1
--auth-user-pass secret.txt
auth-nocache
;redirect-gateway autolocal
;route 10.0.0.0 255.255.255.0
;route 192.168.88.0 255.255.255.0

Upon trying to establish connection between the Client and the Server, everything works as it is supposed except for the TCP/UDP reset connection in the very end :

The configuration files comes from OpenVPN running previously on a Windows Server. I am not sure where the restrictions come from that’s why I am submitting this. I have followed an YouTube video in order to properly configure the Mikrotik device (won’t share the URL now as I suppose this was the reason I had my 1st post not confirmed by the Moderators team).

BR,

this should definitely help

Well, checked the URL you have left me. Thank you. Did not see anything different in the configuration files I have and what the others were discussing.

This is the Terminal output when I logged in:
ovpn,debug,error,l2tp,info,debug,critical,warning duplicate packet, dropping

What was offered when I have tried searching for in here is inapplicable - tried it already as the first time I have tried running the OVPN on the Mikrotik I have had all certificates and configuration files imported. The above was the client’s console error I received back then and now. Then started over and ended up here discussing the misconfiguration, as it is obviously misconfigured.

BR,
T.
