I see. So, is it same thing when network is slow and there is a mistake in url?

The devops changed the url and I had to go through some steps to find out what the problem was.

How do you suggest the SDK know what is the 'right' URL and what is the 'wrong' url?

Slow network or network died all of a sudden - you wouldn't want your experiments to fail just because there is a network issue. Once network is restored - everything is sent as it should be to the backend. This is the resilience I was talking about

Regarding mistake in URL - I guess it is your responsibility to keep track of not using wrong URLs. As I said before - How would you suggest the SDK know what is the 'right' URL and what is the 'wrong'...

This is also used in automated scenarios and over possible network issues, the retry is built in and is a good compromise - basically making the SDK resilient to network issues. The error you're getting is a failure to connect, unrelated to the credentials...

I am passing my credentials as well. So, if it tries with the credentials and it doesn't work, may be try twice, may be three times, then raise an error. I don't know a lot about libraries, but the error that I am seeing is a bit confusing now.
