Pages not indexed but website is checekd and all correct. Then WHY ?!

What the … am I missing ?! Everything is like it suppouse to be. I have 3 clients websites with the same settings and other 2 are working with no issues…
robots.txt - check and I am not blocking anything except admin, but you can check, its a standart robots txt for osclass
index tags on pages - check
uruls active - check, checked also for those errors with online checkers, no problem found, etc.

But Google Search has other mind:

  1. Pages with “Redirect error” - 990 - Same pages do NOT have redirects or whathe f-ing ever, they are also not with changed urls or else.
  2. The page is found - not currently indexed - 840 - ANd WHY IT IS NOT Indexed ?! Just bunch a urls not cheched… Its like that from the last year same time ( july )… I changed and moved my website to an new url and …here we go again…

For 1. - When i do URL check:
The URL is not available to Google
It cannot be indexed. Find out more
Page changed?

Availability
Redirect error
The URL will only be indexed if certain conditions are met
Detection
Not checked in active version tests
Crawling

Crawler
Googlebot for desktops
Is crawling allowed?
Yes
Retrieve the page

Failed: Redirect error

And again the URL is there and it does not contain or it is not an redirection.

For 2. - The same damn error
The URL is not available to Google
It cannot be indexed. Find out more
Page changed?

Availability
Redirect error
The URL will only be indexed if certain conditions are met
Detection
Not checked in active version tests

All those links are the ads published in my website. I am using osclass. Changed numerous damn plugins for SEO, robots txt checked and still no resolved issie… Whet the F is the damn problem then ?!
No one tells. From the devs checked – All fine… Other checkers online and proffessionals sayd that the website is fine… Where is the problem ?! It does not containt any illegal things or whatever, just an classifieds website. It will come to an second year of problems…
