I can't quite remember the exact situation, but I think this turned out
to be connected with the Patchwork service not being compatible with
current versions of the Shepherd, specifically it tries to use
primitive-fork while starting [1] and I'm guessing this leads to
confusing state things happening internally that break SSH.
