Capnproto connection timed out

I have this notebook that uses Pycapnp to talk to a remote server, which works fine locally, but in binder the connection times out: Pyttoresque-templates/tran_live.ipynb at feb4768043444850776f2cead4291a1c1feadba1 · NyanCAD/Pyttoresque-templates · GitHub

I fully expect this to be because of firewall/cryptomining reasons, but I’m wondering if there is a way to do this on binder?
Ironically, capnp is used to offload the heavy computation to another server.

This is the list of allowed outbound ports:

Thanks! I pirated the git port and it seems to work now.
