wait_for_connection silently hangs for 60s

[Half-Shot]

It takes 60 seconds to connect to the HS in wait_for_connection, which suggests it's failed 6 times to do so. However, there doesn't appear to be any logs explaining why it's failed to connect so it looks like a hang. The bridge generally seems to work afterwards, so wondering if I am forgetting something.
