The most common and reliable guide I have found for brokering peace between the geth and the quarian is the following:
In order to achieve peace between the two races, you need to get 5 to
7 points. These points are based on your ME2 and ME3 decisions. If you
have 4 points or below, you cannot achieve peace.-Rewrote the Heretics (0 points)
-Destroyed the Heretics (+2 points)
-Tali is NOT exiled (+2 points)
-Tali has been exiled/You did not do the Loyalty Mission (0 points)
-Resolved Legion/Tali conflict either using the Paragon or Renegade options (+1 point)
-N7 Mission: Save the Admiral on Rannoch in ME3 (+1 point)
-N7 Mission: Destroy Geth Squadron on Rannoch in ME3 (+1 point)
-Completed Legion's Mission in ME3 (or no peace)
Now, I imported an ME2 save where I destroyed the heretics(+2), Tali is exiled, I resolved the Tali/Legion conflict using a renegade option(+1), I saved the admiral on Rannoch(+1) and destroyed the geth squadron(+1). Of course I also did Legion's mission.
This gives me 5 points which is enough to get the option.
I know that I also need 4 bars of reputation…which I think I have. I have about 3.5 bars of renegade, then above this I have an additional bar of what I assume is paragon, as it has a harp symbol and is blue.
This should be 4.5 reputation in total.
From what I can tell I more than meet the options to successfully broker peace between the quarian and the geth, however, I don't even see the options. They are not greyed out; they don't appear at all.
Why?

i think you need either very high renagade or very high paragon score to actually pull it off, this is what i did to make peace
saved the two quarians in ME2 (in the first and second mission you do with tali before she joins your team), rewrote heretics, tali not exiled, saved admiral, did the reaper hack thing, and had a very high paragon score
