Hello,
Thanks for contacting us, and sorry for any inconvenience that might have been caused due to that.
I’ve checked your homepage source code and found it has noindex robots meta tag set there.
I’ve also verified the situation by logging into your site and checking the homepage robots meta settings and found the same here. Here’s a screenshot for your reference:

Please set the robots meta to index, save it and verify that by viewing the source code of your homepage if it’s set to index. If so, the issue should be resolved once Google re-crawl the URL again.
You may also ask Google to re-crawl the affected URL. Here’s how you can do that:

Let us know how it goes. Looking forward to helping you.
Thank you.
