When I published to Azure, swagger ui no longer can access the information from the server. I changed the CorsOrigins setting, is there something else I have to edit?

The Audit Logs and Web Logs do not show anything specific to Swagger. However, I do also have an issue with SignalR not working (yes, I am using .Net 4.6.1 and not just core), that error message is:

Hi,
For SignalR, can you try this #3783@6f1d9bc9-04fc-44e2-99d3-85040ddbe290 ? For swagger, what is the behaviour on the swagger UI ? Can you share a screenshot ?

When I go to the Swagger UI page, I just get this error:
Can't read from server. It may not have the appropriate access-control-origin settings.
By the way, the article you gave me for SignalR worked! For anyone having the same problem... Add WEBSITE_LOAD_USER_PROFILE = 1 to your App Settings on your Web.Host App Service in Azure

As it turns out... I am only experiencing this issue in Microsoft Edge... it works in Chrome. I figured this out when I read another post which suggested that the Login didn't work in IE... I also have that issue... so I tried Chrome and it worked so then I also tried going to my API page and it worked.

Hi @brallierc, I tried it in edge with no errors? Could it be about edge version?
