After upgrading your Pulse One On-Prem appliance to 2.0.1834 and attempt to connect to the admin UI the browser returns 502 Bad Gateway.
Cause
If you were able to connect to the Pulse One UI prior to the upgrade and have confirmed that all services have started it's possible you've run into a race condition that causes some of the data migrations to not complete successfully.
Solution
Currently the only solution is to open a case with support.
