File integrity checksum failed for "hello"

Redhat, Docker EE 18.09.2, UCP 3.1.2, DTR 2.6.1. I am getting this error when I am trying to push images to my DTR. My Proxy is setup and everything. Still no success…Any ideas?

file integrity checksum failed for “hello”

I cannot find my UCP Config File. It send me some weird status
