Please take this constructively, but looking at your shots, you seem to have very poor command organization. It is very important that you organize your divisions into Corps, and keep those divisions within range of those Corps. The Corps should have appropriate leaders (high MECH ratings for Panzer troops, etc), and should be within range of Army HQs.
It appears you have little to no cohesion. A few examples:
1. The shot of AGNs Panzers showed them all HQ'ed to OKH; maybe you changed that though
2. The AGN spearhead appears to be a corps of 2nd Army; I bet that Corps does not have a Panzer General. Also, where is the rest of 2nd Army? Is it in range of Corps/Army HQ?
3. AGN spearhead also has units of 4th Panzer Army, which also has:
-1 Division visible near Belgorod
-What appears to be the Army HQ down by Bryansk
4. 2nd Panzer Army has a random orphan division near Smolensk. The rest of this army is way down by the Black Sea
5. One stretch of line north of Gorlovka shows 4 infantry divisions on the line, each from a different army: 17th, 6th, 11th, and 2nd Panzer
I may be wrong, but you command structure appears to be a mess. You should spend some APs to fix it. Hope that helps!
See the shot below; that's only a dozen or so hexes of front, but I count 8 armies in there, not including the RHG unit:
