Other than normal connection logs, here is what might be going wrong:

D/SyncService: onCreate
D/SyncService: onBind
D/SyncAdapter: onPerformSync; Service not available, account:guest/social
D/SyncService: onDestroy

Later on I get:

I/MyContextHolder: waitForMyFutureContext myContextOut is expired TimelineActivity

If you need higher verbosity, or the full logs (there isn't much to see imo) just tell me. Here is the ssl cipher used: TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
