Have you Seen That , Not index

[Faster01]

Before, all of my pages were indexed.

Later, my hosting plan expired, and it took me some time to renew it.

When I checked afterwards, I saw that Google had de-indexed all of my previously indexed pages.

Please advise me on how I can get all my pages re-indexed so they appear in search engine results again.

thank you

This happens because Googlebot tried to crawl your site while the hosting was down and encountered server/DNS errors, leading to de-indexing. Since your site is live again, make sure all pages are returning a 200 OK status. Then, resubmit your XML sitemap in Google Search Console and manually 'Request Indexing' for your homepage. Give it some time; Google will naturally recrawl and re-index your pages within a few weeks.

Wait few days if its your new site. Or if you want you can fix it manually.

Exactly that should fix it

Check the reason in Google Search Console. Most likely, the crawler hit your site when the pages were returning a 404 (or server error) because of the hosting downtime.
Just give it some time, it should re-index naturally.
