TLS error with client connection

[SKJoy]

OpenVPN GUI (client application) log says;

Sun Jun 23 19:11:29 2024 MANAGEMENT: >STATE:1719148289,AUTH,,,,,,
Sun Jun 23 19:11:29 2024 TLS: Initial packet from [AF_INET]192.168.1.21:1194, sid=4af197a1 be5346b5
Sun Jun 23 19:11:29 2024 tls-crypt unwrap error: packet too short
Sun Jun 23 19:11:29 2024 TLS Error: tls-crypt unwrapping failed from [AF_INET]192.168.1.21:1194

What I did;

• Deployed both OpenVPN Server and Admin UI containers
• Manually created ./fw-rules.sh with default contents
• Manually created server.conf with default contents
• Server running in LAN with IP 192.168.1.21
• Disabled firewall on the server
• OpenVPN Server & Admin UI containers seems to run fine
• Successfully accessing (working) with the Admin UI with web interface
• Updated client profile to use server IP 192.168.1.21
• Created Test certificate and downloaded the Test.ovpn file
• Attempted connecting to server with OpenVPN GUI client application with Test.ovpn profile imported; on another machine within the same LAN with IP 192.168.1.10

My docker-compose.yml file (changed the Admin UI HTTP port to avoid existing conflict);
