Removing Copied Archive on remote server…. Done

I’m still not 100% sure what caused this but I chose to not use compression for the transfer and disabled CSF on both servers and it went fine.

My guess is the firewall on the remote server but I will have to wait for the next transfer to check which one causes this.
