A week ago, my heatit app stopped working. Its just said it aint installed.Tryed to install it again. But it aint working. It says it is installed, but when i try to use it. It says its not installed. Now, its the same with the Ikea app. Wtf is happening???

Try to restart your router and WiFi access point(s). Then restart your Homey.
No luck. Tryed to restart the Ikea app after restart of all network and homey, but im just gets timeout. 
You’d (temporary) disable ipv6 on your router.
If that solves it, report to homey.app/support,
the marked issue below still is not fixed:
Ill try that tomorrow. I do see now, that my switch is dead.. hurray…
Hmmm. Maybe the switch breaking down part was the cause.
My god. That fixed it. Tnx to you both. I would not guessed that it was a network problem.
