My Blazor server app runs fine on Azure with one server. When I scale it out to two servers, I sometimes get the following. I have session affinity turned off. This clearly is the Blazor framework having problems. Any idea why?
Update: I turned on session affinity and the problem is gone. Does Blazor server require affinity so that it can have a series of system files like blazor.server.js all be read from the same server?
