Miele Cloud binding show issues (again)

I need to get back to issues with the Miele Cloud binding.

Even though Miele Cloud is working again, now this binding stalls the Astro binding in my setup.
As soon as the Miele Cloud binding gets activated the Astro binding stops updating its channels.
As soon as Miele cloud binding is paused in UI the Astro immediately starts working again.
It seems the openning of the SSE connection stalls some thread

Please see log (Debug level for Miele Cloud) below:
