Help troubleshooting van system

I've had a Renogy 100 watt on my camper van for a few years and it has worked great. This summer not so much. I was running a Blue Sky Sun Charger 30 and it would never get to bulk charge even when the batter was down to 12 volts. The amp reading was never above 0.2, even in full sun. This didn't used to be like this. It would read 5+ amps in full sun. I tested the panel with a multi meter and it seemed to be fine. 21 volts, 5+ amps in full sun. So I got a new controller. A Morningstar Sun Saver Duo. Hooked it all up and it's showing zero amps in full sun. I got a new battery 95ah AGM. I hooked up the new battery today and I'm still showing zero amps. WTH? I tested again. Panel seems to be fine. Battery from the store with no more charge is at 12.8. What am I missing?
