2-piece toilet leaking between bowl and tank

My toilet started to leak between the bowl and the tank. I took it apart and replaced the rubber gasket that seals the flush valve assembly to the bottom of the tank. I replaced the other gasket (more foam than rubber), the one that seals the discharge tube to the bowl and reassembled the tank and bowl using new brass bolts, brass washers, rubber washers (rubber washers against the porcelain) and nuts. The old rubber washers and gaskets were all looking pretty dry and cracking. I tightened everything until the tank was well secured to the bowl. I would tighten the nuts a little, check if the tank was still wobbling, tighten a bit more... until the tank didn't move anymore and seemed well seated.

I'm still getting a leak from between the tank and the bowl when I fill the tank up. I don't dare tighten any more. I can't tell if the leak is coming from the bolt holes or the joint (I suspect the bolts). The rubber washers seem well squashed. What did I do wrong?

The engineering of a toilet leaves that question to be answered in nearly an infinite number of ways.

A piece(s) of tissue strategically placed will sometimes tell us where the leak is.

Hairline crack or possibly over tightened the bolts to much or uneven. All the toilets I have installed or worked on always had some play between the bowl and tank. The washer placement is also very critical as to what goes where.
No Warranty Means- If it breaks in half you get to keep both halves.
