I have a log nodejs backend code here and it runs on port 8080.
process.env.PORT = 8080 in the environment varisbles.
var port = process.env.PORT;
app.listen(port, ()=> {
console.log("Port is", port);
})
It connects to the databse as I see the output in the log file :
Port is 8080
I get an error in the log file with the following.
/var/log/nginx/error.log
----------------------------------------
connect() failed (111: Connection refused) while connecting to upstream, client: 777.77.7.777, server: , request: "GET / HTTP/1.1", upstream: "http://111.1.1.1:8080/", host: "666.66.66.666"
Does anyone know why it errors?
Should the host: be my elastic beanstalk url by any chance?
If you need any additinal info let me know!

I am a newbie and still learning development. I have deployed a nodejs app on EB2 for a project I am making. While most of the time the app works fine, sometimes it will stop working and API calls will stop going through giving me a '504 Gateway Time-out' error. I checked the logs and here is what I found repeatedly :
2022/09/22 16:18:32 [error] 3377#3377: *3027 connect() failed (111: Connection refused) while connecting to upstream, client: 172.31.2.149, server: , request: "GET /socket.io/?transport=polling&b64=1&EIO=4 HTTP/1.1", upstream: "http://127.0.0.1:8080/socket.io/?transport=polling&b64=1&EIO=4", host: "www.domain"

What is causing this and how can I resolve this?
I successfully deployed the nodejs application to aws elastic beanstalk using gitlab ci/cd. However, when I try to visit the link of the aws environment I get 502 bad gateway error. I downloaded the logs file and below are last logs that I get.

What is going wrong in this case and how to solve it?
UPDATE
Here is the ED platform I am using
Node.js 16 running on 64bit Amazon Linux 2
I am using HTTP for now.
Node.js uses port 3000 by default, but EB uses 8080:
By default, Elastic Beanstalk configures the proxy to forward requests to your application on port 8080.
Your error indicates that your application does not use port 8080, which would explain why EB fails to connect.
I deloyed my Nodejs app to beanstalk service, I am able to Signup and Login my app, but after i Login, it just keeps buffering, not pulling any data, i checked my AWS logs and found this error
2021/10/22 23:43:09 [error] 3610#3610: *1 connect() failed (111: Connection refused) while connecting to upstream, client: ip-address, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8080/", host: "ip-address"
i have changed my settings on my security groups in configuration with no luck, would be glad to get some assistance here. Thank you!
This question already has an answer here:
GET: ERR_SSL_PROTOCOL_ERROR nginx + vue.js

Closed 3 years ago.
I created a brand new tiny webapp with vue cli, so without adding anything, apart from what the empty vue-cli scaffolding brings:
(base) marco#pc:~/vueMatters/testproject$ npm run serve
> testproject#0.1.0 serve /home/marco/vueMatters/testproject
> vue-cli-service serve
INFO Starting development server...

DONE Compiled successfully in 1409ms 8:14:46 PM
App running at:

- Network: 192.168.1.7:8080
Note that the development build is not optimized.
To create a production build, run npm run build.
And got this error message :

How to solve the problem?
You need to specify SSL Certificates in your socket connections.
Here is the reference.
var options = {
key: fs.readFileSync('./file.pem'),
cert: fs.readFileSync('./file.crt')
};
var server = https.createServer(options, app);
var io = require('socket.io')(server);
I got this message

I am using nodejs/express Elastic Beanstalk env.
I have one nginx related file in
.ebextensions/nginx/conf.d/proxy.conf
Upper file contains:
client_max_body_size 50M;
Whenever I try to get my webpage I got 502 bad gateway.
What's wrong with my app?
Just recording my incident here just in case it helps someone or my future self. I had a Django application that had SECURE_SSL_REDIRECT set to True. Since I had no load balancers configured to handle HTTPS traffic I was getting a timeout. Setting it to False fixed the issue. Couple of days wasted on that one.
111 connection refused likely means your app isn't running on the server/port combination. Also check that the security group for your app instance (or load balancer) has an inbound rule set to allow traffic from the nginx instance
I was dealing with this error on my NodeJS application (NEXTJS). Posting this here just in case is useful for someone.
My error was thet the deploy command failed at the build step (next build), which means the Node server never restarted. For that reason nginx could not find the server. You can find this kind of errors in the web.stdout.log
I tested my build command locally, fixed the errors and it worked!
