Nuget restore error on mac terminal

Question

I have a Net6 iOS binding project that can be restored and built in visual studio for mac. However, when I try to run nuget restore in terminal, I got errors.

I tried creating a new Net6 iOS binding project under New Project > Other > Custom > iOS Binding Library. I also tried Net6 Android project, and got the same error when I try to nuget restore in terminal.

Error:
