Max hub connection to Tuya cloud

[Sam+Londonderry]

Having upgraded to sky max I'm now unable to control any of my wifi switches outside of my LAN.  All my switches are offline within the TUYA app but as soon as I switch to wifi within my LAN they are all online and controllable again.  I've reduced the security on my hub to WPA2 however no connectivity outside of LAN.  Any help appreciated

@Sam+Londonderry some devices cannot connectvto the dual band SSID routers likectge Sky Max hub use. Thecworkround is to go into the My Sky app find the hub's advanced settings in the Product Options section. Then temporarily turn off the 5GHz band then connectvthe devicescto the then single 2.4GHz band SSID. Once connected repeat tge process and turn the 5GHz band back on and they should stay connected.

Thanks for your reply.  Just to be clear they all do connect via WiFi  when I'm on my LAN.  However when using the app away from my property using the 5G network on my phone then all switches remain unconnected and offline.   Just wondering why they connect on my LAN via the max hub router dual band but Joe external to it.   My searches have stated it's a connectivity issue with the hub and the external cloud associated with the Tuya/smart HW.  Thanks

@Sam+Londonderry Have you put the old sky hub back on to check, the app is having a problem with the port connection through to your hub while on mobile!

@Sam+Londonderry what do you mean by "my LAN"? LAN is the abbreviated name for your local area network which is normally made up of the Sky hub and eevices connected to it by WiFi or by Ethernet cables. Do you have somecform of a secondary router or similar?

I would do that only I returned it to Sky....I'll try and get an even older one to try this out.  Cheers

That's exactly what I'm calling LAN.   The sky hub and the connected devices within my house, in the case of the switches connected to the hub via WiFi
