AutoML Python SDK, Beginning Model Selection doesn't work. Iteration times out.

It doesn't work further. I tried with a very small data subset of just 100 observations and it worked. When I use it for a large dataset it doesn't work further. it stuck at iteration 0 and finally after 3 hours it times out. I tried with other subscriptions as well and it's the same. It's been 3 or 4 weeks and I am stuck and don't know what to do.

I have already run the same code a few months back and it ran and gave the output. But from the few weeks, it's not working further. I have tried my other old codes as well and they also get stuck here at the iteration.
