Unable to access ROSA Console via site-to-site VPN after cluster installation

Issue

• The ROSA cluster has been installed successfully but the communication to the console through a site-to-site VPN connection fails.
• The console URL is resolvable externally, but the connection times out at the Client Hello during TLS Handshake from the on-premises network.
• There is a Firewall (FW) managing the VPN connection, but no drop connections are observed.
