Closing since based on your response this is network related.

If this were me I'd just switch hosts at this point. Or try something free like Oracle Cloud, or home hosting and use playit.gg to proxy the connection.

Can you connect without running FRP in front? If so then its likely a misconfiguration of FRP.

Given that the connection attempt is logged that implies that you are getting incoming traffic from the client but somehow the response from Geyser is not being sent back to...

I wouldn't call it a bug but something wrong with the networking setup of docker.

You may also need to change Geyser's bind address explicitly to what you are expecting it to bind to within the container.

Hmm so then could you please diagram/clarify the setup you have? FRPC is in Docker... is Geyser also, and on the same machine?

Geyser and the MC server are not running in docker containers as well?

Closing since this is a networking setup issue. For further support, you can join our discord at https://discord.gg/geysermc.
