I have not seen this with the default windows authentication, so it could be an issue with your custom authentication provider. Have you tried debugging that? Have you implemented exception logging in your code?

Thanks for your reply.

 

I'm using the code from github for SQL Server 2017 (this is the most current version of the sample) (https://github.com/Microsoft/Reporting-Services/tree/master/CustomSecuritySample), with minor changes in order to correctly verify the user and password against encrypted password stored on SQL Server coming from IIS forms/custom authentication template.

 

I'll try to implement some kind of logging inside the custom security code for RS or, maybe better, hook the VS debugger on to the DLLs/processes (if that is even possible - I have not done that before).

 

But I think it's some kind of configuration problem with PBIRS website - maybe a timeout.

The problem with disappearing custom visuals seems to get worse if the report page is more complex and PBI and the browser has more work to do. (Firefox seems to work for now)

 

Anyway, if I have some "news" I'll post it here ....

 

Thanks again!
