MongoDB connection failed! Double check the MONGODB_URI setting in Heroku.

Hi! Did you deploy the application on your own server? If so could you show me what you put in your compose.yml (or docker-compose.yml)? This error message usually comes if there is an issue with how you setup the connection between nightscout and mongodb.

I have never worked with mongodb and have no idea where to insert it

[pyrmon]

I see two things that might be the issue:

• For this line: "MONGO_CONNECTION=mongodb://mongo:27017/Nightscout" I think you need to change it to "- MONGO_CONNECTION=mongodb://nightscout_mongo:27017/Nightscout"
  • Apparently I forgot to change the connection string when setting the container name
• Try only the first one and restart the container. If it then works great. Otherwise you can try putting a concrete mongodb version as the image tag. If you are using a Raspberry Pi 4 then it might be that the pi is incompatible with the latest version. I would then make it so the image line says "image: mongo:4.2.0"

[WOLFERSER]

It doesn't work anyway.

I am using ubuntu 20.04 VDS

Hmm that's weird. Maybe the ip range of the docker containers is not aligned. Not to worry as we are publishing the mongo db port to the local port 27017 of the machine maybe it works for you to make this line: "- MONGO_CONNECTION=mongodb://localhost:27017/Nightscout". You can also for testing try to make the port 27017 publicly available and use the software MongoDB Compass to try to connect to your server on port 27017. But make sure to disable the access again afterwards as the mongo Db is not secured.
