Welcome back to the Wefugees Community and thank you for your question.
Unfortunately, the "Duldung" (temporary suspension of the deportation) is not considered to be a "legal residence" (rechtmäßiger Aufenthalt) and therefore these years (while holding a Duldung) can not be counted regarding the requirements for the permanent residence permit (Niederlassungserlaubnis) or naturalization.
I am sorry that I can not give you any more positive news here.
In any case, please don't hesitate to get back to us with any further questions.
All the best,
