[Snapshot Pro] Snapshot Pro Backup will not work

Support Keeps disconnecting; I've had to reenter the following request for chat support about 6-7 times now in 25 minutes.

Snapshot receives 504 GATEWAY TIME-OUT

As per Support Chat instruction; I added the following to config file:

define('SNAPSHOT_TABLESET_CHUNK_SIZE', 10);

define('SNAPSHOT_FILESET_CHUNK_SIZE', 10);

I restarted Snapshot.Tried to back up again and it failed.

Issue still persists.
