Zigbee Connectivity in my house sucks 😢

Ugh, I feel so stupid, once more …

I saw this error message and for the first time did not click it away, but copied it and searched for it:

Failed to send request: Failed to enqueue message after 3 attempts: <EmberStatus.MAX_MESSAGE_LIMIT_REACHED: 114>
EmberStatus.DELIVERY_FAILED: 102

It seems that many people had the same issue before me, but only recently (1-9 months ago):

People are reporting the same error again and again, but no one has a fix.
Broadcast appears to be an issue, but it’s disabled in my case.

They are all reporting that it’s ZHA + SkyConnect stick. Z2M and Deconz are said to behave normally.
For many of them, reloading ZHA helps for some time.

I don’t know what to do either.
