MikroTik is picky about ciphers. If you see “TLS Error: TLS key negotiation failed” in the logs, the server and client aren’t agreeing on encryption algorithms. Solution: explicitly list supported ciphers on both ends. On RouterOS 6.x, stick with aes128-cbc and aes256-cbc ; on RouterOS 7+, you can safely include aes128-gcm and aes256-gcm as well.
Make sure your router’s firewall allows incoming connections on the OpenVPN port (e.g., 1194 TCP/UDP) from the public internet. mikrotik openvpn config generator

If you need to onboard ten different OpenVPN users, manually generating and signing ten client certificates is tedious and prone to mistakes. A generator can batch‑create users, sign their certificates, and export individualized .ovpn files in seconds. On RouterOS 6
