Thanks for reaching out!
Could you please show us a screenshot of the error message? And if possible please share some other screenshots of the steps before the error appears.
I would like to ask you if the network connection you are using on the PC with ISSIoT has any restrictions and if so, if you are able to connect to a network without restrictions to try this procedure.
Also, some users have reported issues like poor performance with ISSIoT due to their antivirus. So, another thing you could try is to temporarily disable the antivirus during this procedure and see if the issue persists.
Let us know.
