foolscap negotiation fails with "unknown TubID"

[Lukas Pirl]

Hi Tahoe people,

I have an introducer and a client, both running on a publicly accessible
server (S). All storage servers are supposed to connect to S.

The problem is, that one of my storage servers cannot connect to the
grid. It is the only one running on FreeBSD, the others are running on
Debian. All instances are installed via PIP.

It fails to negotiate a connection, telling me something about an
unknown TubID (see error pasted below).

How can I debug/solve this?

Thanks in advance,

Lukas
