Devices going offline. Requesting access to the Hub's Beta firmware group

Hello. I have aoetech hub v3 with firmware 59.8 and it seems it stuck in the loop. My devices go online and offline, there no events in journal. I can not control devices from the app. I subscribed to beta firmware but no success. Could support help me?

Hi, @Victor_Weinstein
Sorry for not replying earlier, we already shared the info you shared with us over email.
We sent you a confirmation email since the engineering team already added your hub to the group.

Thank you. I got beta firmware, but it did not help with the behaviour of hub. I will check some other options, and get back.
