Loading devices is working now and indeed the initial problem is still there.

Login is working in portal.iotcreators.com, but no devices anymore.
errors :

1. Something went wrong while loading your devices
2. Something went wrong. Looks like a connection issue, still have an internet connection?

yes, online but my profile, projects and Sim cards are gone. lots of errors also

Can’t login anymore. Profile and sims are gone

I’ve configured the Quectel BC66 for the T-Mobile Netherland network. The module is connected to the network (no errors) Sending message works in the console (SEND OK) but the message isn’t received in the T-Mobile Portal.
My device is registered in the Portal as UDP device and also sending with a UDP socket.
The connection is roaming (5) in the Netherlands?
For elimination I’ve used two different SIMS ans two different BC66 devices. But still the same.
Firmware of the BC66 = Revision: BC66NBR01A07

What am I doing wrong in my configuration?

Thanks
Gerard
