For now, I got this:
If I write on the command prompt: "heroku restart", It works
And if I write on the command prompt: "heroku logs –tail", it shows me again, the first image, it doesn’t work
How to fix this error
Thank you in advance
>Solution :
I’m assuming you are using mongodB atlas. You need to whitelist your IP address. To do that, head over to your network access tab, and include an IP address 0.0.0.0/0. This is a wild card IP address that would allow all IP addresses with the correct credentials to access your DB.
As such:
Note: This whitelists all IP addresses. It’s alright when testing. But when going into production, you might want to whitelist only IP addresses that should have access to the cluster…for security purposes.
