Heroku Deployment - Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

[vincentracine]

Steps to reproduce the behavior

Brand new heroku instance. Deploy to heroku git push heroku master.

Expected behavior

Application starts and binds to process.env.PORT

Actual behavior

Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch. I am debugging process.env and it does have PORT set:

Can you show your Procfile please?

[bassjacob]

And can you confirm how long your application takes to boot in your development environment?

[vincentracine]

@bassjacob Procfile current looks like this: web: node keystone.js but i have also tried web: node keystone.js -p $PORT. Locally, it starts within 5 seconds.

[akopcz2]

Heroku dynamically assigns your app a port, so you can't set the port to a fixed number which it looks like your doing at PORT: '43760'.

[vincentracine]

@akopcz2 I know this behaviour already. My problem is that Keystone is not binding to the port Heroku is setting. As you can see from my logs in my original post that Heroku is setting a port but Keystone isnt starting.

[bassjacob]

without seeing more information from the repository, this is going to be hard to debug. Have you raised this with Heroku?

[vincentracine]

Found the issue! I removed this from my package.json

"engines": {
    "node": ">=0.10.22",
    "npm": ">=1.3.14"
  },

When Heroku uses the default node version, it works perfectly!

[bassjacob]

ah, that's great to hear :smile: Thanks for reporting back.

[james-lukensow]

Just has two sites that encountered the same issue after working for months, then having to do a hotfix today, the above error was encountered. Removing the "engines" from the package.json allowed the app to start without error.

[JedWatson]

I've pushed a fix that removes engines from the package.json, which will hopefully resolve this for good.

[capitola-dev]

@JedWatson I'm not sure in which project you removed it but the keystone starter has still those lines. Removing them makes Heroku work

[MetaNaveen]

The below steps resolved my solution:

Editing package.json as:

... "engines": { "node": "5.0.0", "npm": "4.6.1" }, ...

and Server.js as:

... var port = process.env.PORT || 3000; app.listen(port, "0.0.0.0", function() { console.log("Listening on Port 3000"); }); ...

I have this problem too, but in Python web app.

How to fix this? It's a telegram bot, it only works for a minute. UPD Yes, I know that this is a js repository, I just did not find any more information about this error. Thank you in advance

[camu891]

@frozyeah i have equal problem but in java project(jar executable).Have you Any solutions? Thanks

[ghost]

@MetaNaveen , guy, thanks a lot. especially for the second part of your decision (server-side) it helped me

[anakib1]

@frozyeah have you fixed your peoblem? I have exactly the same error, first time i launched the app everything was good, but on second start I have same error State changed from crashed to starting Starting process with command python PythonBotEcho.py Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch Stopping process with SIGKILL State changed from starting to crashed Process exited with status 137

@anakib1 This GitHub issue queue is for bugs or feature suggestions related to the Keystone JS Framework.

If you have general questions on using Heroku, please try Heroku Support resources or post a question on Stack Overflow with details relevant to your question.

Thanks, Stennie

[abdoutelb]

This happened to me when i write a static hard coded port number. using process.env.PORT || 3000; to be listened solve the exact error.

[ghost]

Maybe you need change web: filename.py to app: filename.py if it's telegram bot

[anakib1]

Thanks to everyone. @bogi7up your solution helped.

[sakshi30]

I am still sufferring from the same issue, Web process failed to bind within 60 seconds of launch. I have applied all fixes mentioned above. Please guide me

[ghost]

@sakshi30 Need more details.

[sakshi30]

I was trying to deploy a mean stack project on heroku. In my server I am listening to process.env.PORT || 3000; dynamically. My mongodb is also deployed with mlab. Still I am facing the issue Web process failed to bind $port within 60 seconds of launch. and app crashes.

[AviIhej]

I too am experiencing this same issue in 2018. Any help?

[kmiddlesworth]

I've experienced this, too. You can send a support ticket to Heroku asking for more startup time. They will add another 30 seconds for you.

[BisratYalew]

I solved the problem by changing the Procfile.

change web to worker

and then, if it do not work, on the heroku cli type the following: $ heroku scale web=0 worker=1

[asheux]

When deploying an application that uses webpack to heroku, I got the same error and my solution was:

• I changed my server.js to include this code

  
  var express = require('express');
  var app = express();
  var path = require('path');

app.use(express.static(dirname + '/')); app.get('*', (req, res) =>{ res.sendFile(path.resolve(dirname, './src/index.html')); }); app.listen(process.env.PORT || 8080);

- Then added a ```Procfile``` with the following code

web: node server.js

This simply tells heroku which port to use and also which command to use when starting the server remotely. Since, you know, when heroku starts the server using ```npm start```, it automatically listens to the default port. Therefore when you specify in Procfile the command to start the server, heroku will use the port you specify.

[AlanFonderflick]

Hi folks,

I had this issue and fixed it. It's a binding error between keystone server and heroku configuration. It means that you're not listening with heroku on the right port or the right host.

In my case, I had to set the host on 0.0.0.0 and not 127.0.0.1 as recommended on heroku support. Here is the link regarding a r10 error : heroku Error R10 help .

Hope it will save you 3 hours of productivity.

[Santoshah]

Thank @AlanFonderflick This was my code before const PORT = 3000;

and I changed it to const PORT = process.env.PORT || 3000;

Yuhuuuu. it worked. Thanks for saving 3 hours of productivity. :)

[LocalCiggyShop]

what do you put tin the .ENV file

[kuzaster]

I solved the problem by changing the Procfile.

and then, if it do not work, on the heroku cli type the following: $ heroku scale web=0 worker=1 Thanks! It's helped me, but without web=0: $ heroku scale worker=1

Im facing the same challenge when trying to deploy with heroku my stripe backend, i tried to remove engine configuration but it still doesnt work...

This is the log from heroku, help please... The repo im trying to deploy is from stripe starter strapi-starter-next-ecommerce

[tomasignacioc]

Found the issue! I removed this from my package.json

"engines": {
    "node": ">=0.10.22",
    "npm": ">=1.3.14"
  },

worked for me too!! thanks!

Hi, There!

Can anyone help me what is the issue with R10 Boot Timeout in , it seems PORT and DB URI is connected and the server is up and running

P.S: Deploy NestJs Backend in Heroku.

[apfel-das]

Following lines solved my problem on FastAPI - Python3.9.11 (by altering my Procfile).

web: uvicorn api:app --port $PORT --host 0.0.0.0 

where api.py is my code's entry point

@sounishnath003 same here. I changed DB url and this happens, my code already has the :fix: that works for everyone else here. Please reopen this

[elvinagam]

Just spent several hours on this coz I did not read the docs at the first place))

if you are developing an app which does not need UI, then use worker instead of web on Procfile.

In the procfile, instead of using: web: python app.py use this: worker: python app.py

after you push everything to heroku git, make sure to: heroku scale worker=1
