Making external requests and connecting to mail server

Hi :) I have a node application running in a droplet on a docker container. It works just fine on my local environment. I am unable to make external requests using the python urlib request library, and also unable to connect to an external mail server using nodemailer’s transport method. My intuition tells me we are being blocked by DigitalOcean. I have checked my network firewall settings (it is off) and my UFW settings. Please let me know if you have any ideas, thanks.

Hi @humeoneteam,

Which ports are you using? By default for new accounts, port 25 is closed. I would recommend trying with port 587 instead and seeing if that would help.

You can try using telnet from your Droplet to your service’s IP address to see if you would be able to connect as well.
