Recently my webmaster got the below email from Google.
Dear site owner or webmaster of (site name),
We've detected that some of your site's pages may be using techniques that are outside Google's Webmaster Guidelines.

Google Search Quality Team
We removed all external links from the home page and made all links in the blogposts no-follow.
Site dropped its 70% traffic and revenue since this penalty.
All the contents on the site are 100% unique and the site was regularly updated.
After we made all these changes and sent reconsideration request to Google but the site in question got rejected 3 times by Google.
According to Google's last email site still has some issues which doesn't comply with their quality guidelines. We are trying to find the issues with this site but nothing more found yet.
Can any expert tell me please what are the exact issues with this site, how to find them and remove the Google penalty from this site.
I will be very thankful for any help.
