Blazor Server Application hosted on Azure with SignalR. Application is accessed by 200K users globally, we are facing issue with one specific user not able to login to Blazor Server App. Anything to do with proxies are firewalls, unable to track.

Error: Failed to complete negotiation with the Server: Type Error: Failed to fetch - blazor.server.js. Appreciate responses.

    @Arun Siripuram , if all but one out of 200K users can't access your Blazor app, what's special about this particular user? You're stating that you aren't able to track this customer's request to see if they're behind a firewall or proxy server? Are you able to reach out to this customer directly to get that information?

    To determine what's going on with this particular client, I advise going through the client request troubleshooting guide. If you need additional help with your findings, please comment down below.
