I haven’t tested this on IOS or Mac no, I expected the internal socket functionality to work in exactly the same way.
Apparently this is not the case.
I will try to find out what causes this.
The linked thread sadly doesn’t have a solution yet, but it did give me some ideas though.
Do you by any chance know if it works on Macs or not?
If it’s just on IOS, it might be a permission or certificates problem.
