Web logon works. Login from app says Server can’t talk now…

I think we gonna need at least a little more information. Are you connecting to a local server or the cloud services? Is there any firewall active between your phone and the internet connection?

We don’t have any web login functionality. If you are using the same credentials as for forum, it won’t work. Forum account and Blynk account are disconnected.

Most likely a firewall problem. I had the same within our company network. Through 4G or home netwerk no problem,
