> Thanks for the verification. I’m not an expert in ACD but It’s sounding like an oddity in how their system works so I’m not sure exactly how to address the problem (other than the suggestion I made to kenkendk in my previous post). Just out of curiosity, does enabling --no-backend-verification help at all? (This isn’t a fix so much as a test…)

I’m trying add option **–no-backend-verification** set true

It’s works, but doesnt upload dblock
