Big-IQ - After update to 8.0.0.1 - Services Stuck on "Waiting for discovery..."

So, since the F5 support was not able to even understand the problem or assign it to a technician that is even remotely close to my timezone, I ended up in deleting all devices and reimporting them.

But guess what, I just updated to 8.1.0.1 and tried a "bulk rediscover" as mentioned in the upgrade manual -> same effect. IT IS STUCK AGAIN. I luckily tried it with only 6 devices.

I am so tiered of this. I never encountered an upgrade of BIG-IQ without any major problems afterwards....
