PBN Post getting Indexed/DeIndexed Daily?

On 25th March I published 2 posts on 2 domains. The posts got indexed fine on the 26th, however on the 27th they were gone from Google, then on the 28th they were indexed again and now on the 29th they are gone again. The main site and all other pages are fine.

Any ideas?

this has happened to me as well. you are just fine. its just issues with g most likely. i would go through add a sentence to the article and an interlink and should be just fine
