Hello again dear masters:
1- We never had http in our website , always redirect from http to https, from day 1
2- There is no any http url inside our pages , all of JS,Images,CSS .. all are https
3- SSL certificate is fine (Not expired)
4- Similar pages were indexed properly
5- New pages (at lease 30 pages) starting from 13th Sep, are not getting indexed and after inspection it shows:
HTTPS is invalid and might prevent it from being indexed >> HTTPS not evaluated (Under 'Enhancements & Experience' section)
6- When trying "Live Test URL" it says: 'URL is available to Google' , no Error at all
7- There is no any error in 'Settings --> Crawl stats'
Any idea?
