I've been trying to find a good free server for our school project so I've decided to try ec2 and just make my pc the server that I will use. I've managed to install my node server onto the ec2. I can post requests using postman but when I'm trying to fetch data from my html file to the ec2 instance, it says:

Fetch API cannot load ec2xxxxxx.amazonaws.com:3000/login. URL scheme "ecxxxxxxx.compute-1.amazonaws.com" is not supported.

Is there any workaround for this? Thanks in advance!!!

Follow these steps:

1. Make sure your application is listening on port 3000: netstat -anp | grep 3000 also telnet 127.0.0.1 3000

2. Then make sure that local firewall is configured to allow incoming access to port 3000 OR disable local firewall to do a quick test (service iptables stop). for linux, its usually iptables

3. Allow incoming access to port 3000 in your AWS security group.

The error is literally telling you what the problem is:

"URL scheme... is not supported"

Do you know what the "scheme" portion of a url is? This link should help, but it's the something:// portion of a uri/url.

So it indicates that you need to specify a scheme that will get you to your aws server, which is likely either http:// or https://

So to be clear your fetch needs fetch('http://ec2xxxxxx.amazonaws.com:3000/login').
