IPFS/Nginx Port 2001

Question

I have been resolving issues related to IPFS access and it seems the design is that 127.0.0.1 is used for local updates with an API interface to a app. I have 5001 access issues and I have checked already IPFS CORS.

Here is the error -

POST http://jenbil.com:5001/api/v0/cat?arg=QmU5KhkgvweYgE3Gsr8A19uFQrq7mszx7dubcoo89cTmAV&stream-channels=true net::ERR_CONNECTION_REFUSED

I have this config -

And the config file for Nginx

server {
    listen 80 default_server;
listen 8080;
listen 5001;
listen 8180;
    listen [::]:80 default_server ipv6only=on;

#   index App.js index.html index.htm;

#server_name _;
#ssl    on;

    location / {

Answer 1

What are you trying to do with this request to IPFS?

cat is a read operation, so you should use the HTTP GET action, not POST, with /api/v0/cat.

Answer 2

You need to set the IPFS host to 0.0.0.0

ipfs config Addresses.API /ip4/0.0.0.0/tcp/5001
ipfs config Addresses.Gateway /ip4/0.0.0.0/tcp/9001

You may also need to set CORS:

ipfs config --json API.HTTPHeaders.Access-Control-Allow-Origin '["*"]'

Restart IPFS daemon.
