I hit this issue today after upgrading to 1.7.0.3.
I’ve tried to deploy to testing with --debug but this times out of Galaxy. This seems to affect at least 5 users and no workaround is known. Given it affects deployment to Galaxy ie. the very element that makes the MDG money, I find it pretty annoying that it’s closed this quickly.
If anyone at MDG can look through this based on my reporsitory I’m happy to share this code base in which the issue can be replicated.
