I am currently using MTG 10.9.3.
I am continually getting a 504 error during simplification:
Simplification failed with the following error:
Unspecified error during upload: 504 "upstream request timeout"
Do you want to restart simplification again?
I have restarted numerous time at this point.
I have also started from scratch again.
What is up with this?
Are your servers having issues?
