Thanks for all of your troubleshooting efforts. However I still cannot replicate this issue on any of my units. What you’re saying certainly makes sense, a missing route and a down interface would cause these problems. Also, ZT doesn’t ever bring its interfaces down unless one leaves a network, so if it’s down, I strongly suspect something else is setting it to that state.
A little info on my main test setup:
- DS216+II
- DSM7
- Docker version 20.10.3, build b455053
- Did not use docker compose
- Nothing else other than stock applications installed
