fyi, there is no problem when i use public server

[stepht]

Not sure if this is helpful. on machine 1: i start the relay with: croc -relay again on machine1: I use another croc process to send e.g: croc send -c passphrase contents/ on mauchine2: croc -yes passphrase

update: running relay server without docker and passphrase worked, but I will keep this issue
