Why is my Wholesale Pricing App not working anymore?

This App this morning just stopped working!!! It was working last night. Anyone else with the problem or solution??? When I click on it I get this:

502 Bad Gateway


nginx/1.18.0 (Ubuntu)

Hey, @BonikaShears do know the exact name of the app you are using? If so, I could provide you with their support contact info so that you can inquire about the status of their app and if there is a known outage with the app at this time.

If there is anything else I can help you with, please let me know.
