Certificate issue

[francesco.tagliento]

Hello
I have configured OpenVPN GUI 11.43 to connect a VPN server configured with openvpn server. The VPN server is hostet on a Mikrotik router.
When we try to connect we receive following error on GUI client:

2023-08-08 09:25:04 VERIFY ERROR: depth=0, error=unsuitable certificate purpose: C=TO, ST=Italia, O=Axce, CN=CA, serial=710794933130557795
2023-08-08 09:25:04 OpenSSL: error:0A000086:SSL routines::certificate verify failed
2023-08-08 09:25:04 TLS_ERROR: BIO read tls_read_plaintext error
2023-08-08 09:25:04 TLS Error: TLS object -> incoming plaintext read error
2023-08-08 09:25:04 TLS Error: TLS handshake failed

Could you help to solve the issue?

Thanks
Best Regards
Francesco
