Shelly Plus H&T no connection over VLAN

[SteffenDE (Steffen)]

Hi,

I’m new to Shelly but working with HA and networking successful for years.

I try to add a Shelly Plus H&T placed at a IOT WLAN but I can not get connection from my HA VLAN to the Shelly at IOT VLAN. Strange is that I allow any traffic from and to the VLAns on the Sophos UTM. I saw no other blocked traffic but I can not connect?

Anybody could realize that with the Shell Plus H&T?

PS: I can ping the Shelly and same situation for example with localTuya intergration is working fine.

Thanks for any hints!

I got it running, the Sophos Web Protection Filtering do not show blockings, but if I skip for the Shellys I can connect to Plus H&T.
