I installed a virtual iot box on my Windows system and then connected it to my new Odoo 16 database using the pairing code. This worked perfectly, but when I try to interact with the devices in the IoT Box, I always get the error "Connection to IoT Box failed". I also tried it with the standard pi image on a pi. But here, too, the same error occurs. Setting up a new Odoo database did not solve the problem either. Does anyone have an idea to solve the problem?

Thanks!
