I get a message from GCS “Indexing request rejected”

Hi. Something strange…
Website: https://www.hike-israel.com/
This morning I noticed that my website stopped appearing on google search on certain queries. On other queries where it appears, it does without any meta description.
I am talking about queries that the site is on for years on page 1 and have dozens of backlinks and internal links. (even the homepage).
When I inspect these URL’s in GSC I get two types of messages:
1)”URL is not on google”
Or
2) “page indexed without content”
When I press “request indexing” I get the message: “Indexing request rejected”
WHAT TO DO?
(I can send the relevant screenshots)
Thanks
Erez
