Found out that this may is the issue for the server not starting: TechReborn/TechReborn#2128
Startup hangs in techreborn.blockentity.generator.SolarPanelBlockEntity.updatePanel(SolarPanelBlockEntity.java:79) but the hang is caused by a different mod.

Updating to Expanded Storage 5.1.2+1.15.2 fixes the server issue
