Doesn't look like this is being solved.
But I have another problem. I had alerts setup on my account and they are triggered now and I can't remove it since I have deleted my account.
Can you please remove everything from my old account so that I don't get any alerts?

Ok.
They are waiting for logs

Any progress?

Ok. No useful logs that I can send to telldus?

Have you been able to trace the traffic?

Yes

1. Yes. No problem
2. {"client":[{"id":"62174","uuid":"bd252332-1244-4501-8503-960da38e1c5c","name":"Bj\u00f6rnb\u00e4rsv\u00e4gen 12 Local","online":0,"editable":0,"extensions":0,"version":"2.1.1","type":"TelldusCenter","ip":"213.112.xxx.xxx"},{"id":"80645","uuid":"639edb95-f0f1-4224-b8e0-7eb20da1daa2","name":"Bj\u00f6rnb\u00e4rsv\u00e4gen 12 Net","online":"1","editable":1,"extensions":1,"version":"17","type":"TellStick Net","ip":"213.112.xxx.xxx"}]}

(chaged the IP address)

Ok.
I have tried to access my devices again and still get the error.
Just to let you know. I'm able to log in but I get the error when I try to access my devices or sensor

I just tried and got the same error. Time 09:58 

Can I get a printout of the error that you get so I can forward it to Telldus?
