Configuration Details
Have run gravity-sync config on both sides. On Synology have ensured that rsync is enabled etc.
I do note that when I run gravity-sync config on Synology side that it prompts for the Pi password multiple times (5-6x), which makes me think that the passwordless SSH from synology side is not completing correctly. It completes successfully however...and presumably if I am doing gravity-sync push from the Raspberry Pi side, it shouldn't matter (as passwordless ssh to Synology is working). Thoughts?
