How to activate ReSharper if it shows "Logging on..." message in the license dialog

Problem

After checking the box to Use JB Account in ReSharper | Help | License Information the status next to it just shows "Logging on…" and does not proceed.

Resolution

1. Check whether a proxy or VPN is turned on, and see if the issue persists without it.
2. If this didn't help, then collect a log file with an enabled Licensing trace scenario as described in the article and contact the support team.
