Can't sync because can't auth due to timeout

[kode54]

Syncing suddenly requires re-auth, and re-auth fails after passing through the web interface. The web interface successfully loads localhost:8080 and displays the notice about closing the browser, but then Python hangs. Hitting SIGINT produces this backtrace:

Maybe disregard this, it seems my IPv6 connectivity has gone dead, hopefully only needing a reset.

Yeah, disregard, sorry. I didn't realize my machine's IPv6 wasn't working, even though my network's was. Resolved.
