I have a client that has several PowerBI Pro users that connect from all over the world.
Recently, a serious issue has risen: some users suddenly could not see custom visuals, nor import them from pbix files, not even in their workspace.
When they publish a report with custom visuals from the Desktop version of PowerBI to their workspace in the online service, the custom visual simply disappears. If they try to import it, nothing happens (no error messages on the ui, but the visual isn't imported).
By checking the browser console, I see a lot of errors for these users when I load a report with a custom visual or try to import one, here's an example:
These errors do not happen for users that don't have this problem.
Any help and suggestion is appreciated, because this is seriously affecting several users and geopardizing our contract with the clinet.
Solved! Go to Solution.
Thanks for the hints.
Turns out, the problem was with our internal firewall that was silently blocking some addresses in the Microsoft cloud.
Sorry for wasting your time.

Hi @Master_T
Does this issue occur on all custom visuals in the report or some specific visuals? What web browser are you using? Does this issue occur if use other browsers?
