Fix Domain and Gmail Issues

I'm facing issues with both my domain and email, and I'm seeking someone with expertise to resolve them. My domain isn't functioning properly, and I'm not sure if it’s configured with the correct nameservers. At the same time, my Gmail account seems to be affected, and emails are not working as expected. I need someone who can diagnose the problems, verify the domain setup, and ensure that my email is fully operational. If you've handled similar situations before, I'd love to hear from you.
