I'm having some issues with the Attribute Table widget in a web app I created - no attributes will load.
Looking at the developer console in Chrome I am getting an error that I am trying to load mixed content. The URL the error is highlighting is the old map service REST URL I was using before a reverse proxy had been set up to allow the service to be reached via HTTPS.
The map service, and web map data sources have all been updated in AGOL but this issue still persists.
Additionally, if I create a new web application and load the same web map I am currently using in the app I am having the issue with, I no longer get this warning.
Any ideas why my web app is still trying to access the old REST service even though it has been updated?
