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.

Dear @nayelyz . I solved the problem by purchasing Open WRT router and configuring special rules for CDN. It seems that SmartThing hub could not connect with some endpoints due to internet restrictions in Russia.

Hope this helps to other users from Russia, who still uses Smartthings hubs.
