when using the copy to clipboard command in pi at the end I got this result Set the IP of the Mender Server: [127.0.0.1] Please enter a valid IP address: Success!
If there is a chance in the past you removed / blacklisted this device? I did something like this in the past and result was device not showing up in the web UI as it was considered as decommissioned.
@sushkoi Any chance that we can get that command for further analysis? (please make sure not to copy here the secret token - we are interested in the command line options passed to mender-setup )
In short, there was a miss-configuration in EU hosted Mender that was creating a faulty bash snippet for you to copy-paste into your device. This mistake was introduced earlier this week and it is fixed now.
