mongodb connection issue

[JimZam]

Good morning. My Nightscout in Fly was working yesterday but today I get the following error. How can I solve it?
Thank you in advance
Kind regards

Oops - Nightscout is having trouble

Don't panic, we can work this out! This happens to the best of us.

Check the errors below and then refer to the troubleshooting documentation.
Errors occurred during startup:

Unable to connect to Mongo
MONGODB_URI seems invalid: connect ECONNREFUSED 3.224.32.###:27017

Did you try to restart your app? https://nightscout.github.io/troubleshoot/fly.io/#restart-your-app anything obvious when you look at your database in MongoDB?

@psonnera It worked!! I've spent all the morning trying to figure out what was happening (absolute noob here, just copy and paste...).
Thank you so much psonnera

This happens to me on a daily basis (at roughly 3~4am) while running Nightscout on a container, is there something that happens routinely within Nightscout that would cause this? I am not seeing any logs on the Mongodb container or my docker host that give any indication of an error or issue that would cause this lack of communication and it takes nothing more than recycling the Nightscout container to restore connectivity.

@billyjbryant which MongoDB container version are you using?

[billyjbryant]

@psonnera mongo:4.4.18

@billyjbryant do you use logging purging? https://github.com/nightscout/nightscout.github.io/blob/944b213970bed25226a3149c48a2395d09ab41c9/docs/_static/docker-compose.yml#L3
