I was using https redirection just before adding cors middleware and able to fix the issue by changing order of them
What i mean is:
change this:
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
...
app.UseHttpsRedirection();
app.UseCors(x => x
.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader());
...
}
to this:
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
...
app.UseCors(x => x
.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader());
app.UseHttpsRedirection();
...
}
By the way, allowing requests from any origins and methods may not be a good idea for production stage, you should write your own cors policies at production.
