Cloudflared tunnel not working in Github Action runner

I’ve tested the ssh key using SSH port 22 without cloudflared tunnel and know that I am able to connect from the Github runner host to my vpc host but when using cloudflared tunnel, it does not work. I’ve tried adding every possible HostKeyAlgorithms but still didn’t work. Is this an issue with the Github runner or cloudflare tunnel? I am able to connect to my vpc host using cloudflare tunnel fine from my local machines using the same ssh key so I know cloudflared tunnel is configured correctly on the vpc host.

Others are also having same issue on Stackoverflow without a solution.
