A "504 Gateway Time-out" error page is seen when trying to access the myPhpAdmin page.
A loading icon spins continuously next to the database icon in the top left of the index page in myPhpAdmin.
An HTTP 504 pink error box appears when loading the index page in myPhpAdmin, or when trying to load the tables within the database where the loading icon continuously spins.

Refer to KB-1530 to kill processes initiated from phpMyAdmin.
Create a case with Appian Support to investigate the potential offending long running query.
This article applies to all versions of Appian Cloud.
