can NOT subscribe anymore to rstatus account from statusnet

[Erkan-Yilmaz]

1. OK: subscribing still worked on the 15th September from my statusnet (SN) server to account (2a)
2. but then neither from my server (version 1.0.1) nor other SN servers (version 1.1.1) this succeeded
3. also tested with a 2nd account (2b)

My statusnet log shows for account (2b) this error (1)
in your logs you can search for errors for these 2 accounts (2)

further info:

• if you can tell me other rstatus nodes, we can try there also this scenario
• this is a statusnet server and NOT a pump.io server (mentioning since asked in email communication today)
• nothing more done

I also tried to subscribe to a rstat.us account from my GNU social account but failed. Apparently @Erkan-Yilmaz account does not exist anymore but I tried with @wilkie 's http://status.wilkie.io/users/wilkie. I am not sure on how to debug this but I'd do my best for helping (perhaps it's a problem on my side...).
