hacklschorsch	Hi Guest46!
hacklschorsch	What's your shares.needed / shares.total / shares.happy configuration? First thing that comes to my mind is maybe the client is looking for more servers than the grid has available

hacklschorsch	(looks well like it could be a problem with the code though)
hacklschorsch	What OS and Python are you running this on? Would be great help if I could reproduce the issue
Guest46	hacklschorsch Python 3.11.2 on Debian 12. All shares are set to 1 on both server and client nodes, and all nodes use Tor
meejah	Guest46: is it possible to try without Tor, to eliminate one variable?
Guest46	meejah I tried but don't know how to set it up, get "connection refused" from server when connecting to introducer, it's easier with tor :D
meejah	hacklschorsch: restarted
meejah	Guest46: hah, glad to hear something is easier with Tor ;) (i do have an ssh Onion service for that reason too though ;)
meejah	Guest46: can you try with "force_foolscap" in the "[client]" configuration? (theory being maybe the GBS/http stuff doesn't support Tor yet?)
