Nodes Failure - An unexpected error


We’ve been using render manager and it used to work fine till we migraqted to a new Qnap System.
After that whenever we assign a job the nodes keep giving error of:

  • An unexpected exception has occurred in the network renderer and it is terminating.
  • Unbalanced Closechunk - Error Loading File unsupported save version:
  • Jpeg error

Many thanks for any help.
