Mikrotik RB760IGS OpenVPN - configuration

RouterOS Beginner Basics
1

Hi, I’m trying to set up Mikrotik router model RB760IGS with public IP so I could connect through OpenVPN and have access to a network that is behind that router. So far I failed and no tutorials from yt or internet sources helped. Is there anyone who could help me with configuring this router step by step? Just to add, other router (Netgear) worked like a charm with OpenVPN and public IP so there is no issue with my network.

My Client.ovpn file configuration:
client
dev tap
proto tcp
remote <my_public_ip_here> 443
resolv-retry infinite
nobind
persist-key
persist-tun
ca ca.crt
cert Client.crt
key Client.key
remote-cert-tls server
cipher AES-256-CBC
comp-lzo
verb 3
;mute 20
auth-user-pass secret.cfg
;route 10.10.11.0 255.255.255.0 192.168.2.1
disable-dco


My OpenVPN app gets stuck on “Mon Sep 16 02:23:59 2024 MANAGEMENT: >STATE:1726446239,TCP_CONNECT,”

Ok, I removed all rules from my Firewall on Mikrotik router and I ended up with those lines in my OpenVPN app:

“Mon Sep 16 02:45:24 2024 VERIFY ERROR: depth=1, error=certificate has expired: CN=CA, serial=2128042020433817611
Mon Sep 16 02:45:24 2024 Sent fatal SSL alert: certificate expired

Mon Sep 16 02:45:24 2024 TLS Error: TLS handshake failed
Mon Sep 16 02:45:24 2024 Fatal TLS error (check_tls_errors_co), restarting”

Does anyone know how to solve this problem?

First make sure the date and time is correct on both devices. Secondly please send the logs from the Mikrotik device, before you do this it would be best if you added OpenVPN in /system logging to display more information for debugging.
