Hello Everyone,
In my .Net 5.0 Webassembly App the GetFromJsonAsync call produces a 401 Unauthorized Exception when accessed via Iphone. It works fine on all windows browsers even on macbook via progressive web installation. Only Iphone does not work. I can login that works fine but I cannot access my WebApi Controller by any nothods that I have via Iphone.
Any help would be greatly appreciated!
Thanks a lot, kind blessings, Andreas

    You would need to explain what authentication you are using to get help.

    Thank you for your answer!

    I use all standard out of the Box .NET 5 Webassembly Project in VS.
    I think it is WebAssembly and IdentityServer4 authentication?

    What I noticed, after I published it again and copied my certificate fresh on the server it worked all of a sudden. Did not change the code.

    Not sure why, was that because of the certificate?
    Thanks! Kind blessings, Andreas
