Running on Synology NAS

[brandnewant]

Firstly - newbie to docker and Linux, so apologies in advance!

I've followed the instructions but my mongodb keeps erroring and I can't figure out why. At first I read through the logs and it kept complaining that my hardware doesn't support AVX, so I tried altering to the yaml to download version 4.4 (the last before AVX requirements) - see attached.
compose.txt.

The compose error I get is: Dependency failed to start: container for service "mongo" is unhealthy

Logs (such as they are) for the Mongo container are also attached. whishper-mongo-1.csv
