'TLS Error: TLS handshake failed' on OpenVPN client

Good Morning, I am having a problem connecting to the OpenVPN client, even after I tried the alternate TCP configuration. I couldn’t find any solutions online.
I always get:
TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
TLS Error: TLS handshake failed
Although my network works just fine on any browser. How can I troubleshoot this problem?
