Xamarin and SignalR cannot connect

Hello Everyone,

I'm having a strange issue with Xamarin, I am trying to connect it to my SignalR Server hosted in Azure however when I call StartAsync() on my connection it seems to just hang - I don't get any errors or crashes. Does anyone know why Its doing thi?

My Code:
`connection = new HubConnectionBuilder()
.WithUrl("MYURL", options =>
{
options.AccessTokenProvider = () => Task.FromResult("eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1bmlxdWVfbmFtZSI6IjcxZjE4YWFkLWM1NmItNDU3Yi05NzE5LWY2ZDg0YmRjMjdjYiIsIm5iZiI6MTU0NzgyMzEyMSwiZXhwIjoxNTUzMDA3MTIxLCJpYXQiOjE1NDc4MjMxMjF9.QMKN2kn0Rqvnt7lGaZAu1rSgncuLdOy7ioEArQa-FZw");
})
.Build();

try
{
await connection.StartAsync(); <-- This is where the code gets to then hangs.
}
catch (Exception ex)
{
throw ex;
}`

I have tried break pointing through the program and it always hits StartAsync() and then just hangs.

Any help would be appreciated!

Thanks,
Joe
