ProxyJump is to connect to one SSH server by another SSH, right? It doesn't work against GFW. GFW throttles SSH traffic across borders to ensure that SSH can only be used for running commands rather than tunneling data.
Yeah I assumed that's what you were doing, since you mentioned Github blocked specifically. If you need to proxy through a protocol other than SSH, likely need to keep using ProxyCommand.
