Couldn't fetch api while firewall is enabled.


I have a website on digitalocean and I just followed the tutorial down below so i got my certificate and now my website uses https protocol.

Everything is good to this point.

But there is a but. :)

I’m using node.js on my website. It connects to my mongoDB cluster and it creates an api url based on my domainname or/and droplet IP address.

For example my API_URL is: I fetch that URL and do somethings on my website based on items.

But as i followed https protocol tutorial, i just enabled my firewall and because of that i guess, firewall is blocking my API URL and i get error on fetch.

I also can’t reach that API_URL( manually.

While firewall is closed i can fetch my api.

What should i do?

Thanks. Regards.

Hi, Since you followed the tutorial, I guess you configured firewall rules using ufw management tool. If I am right, list the rules and check if communication is allowed on port TCP 5000

sudo ufw status verbose

If it is not allowed, you can allow it adding a rule:

sudo ufw allow 5000/tcp

Here is the tutorial on configuring firewall with ufw management tool:
