I'm having the same problem. I've looked at these configurations files but I havent been able resolve it. Please help me if you know it. Basically the frps is hosted on a server with a public IP, which I can only ssh into with a ssh -i ssh_key username@public_ip (exactly like how you would do with AWS). Here's my config file

Hi @darld , I've able to solve the problem. Thanks

I able to connect now as I need to change the 7000 port from ipv6 to ipv4 in the Aws ec2 instance security. But even connected, but my port of local server still unable to exposed to public internet.

Could you make a screenshot on the log on both the server and the client ?
