Port error when deploying with Fly
When I try to deploy using fly.io. I use the exact commands and ahve not changed anything about my code. I get this error:
WARNING The app is not listening on the expected address and will not be reachable by fly-proxy.
You can fix this by configuring your app to listen on the following addresses:
- 0.0.0.0:3000
Found these processes inside the machine with open listening sockets:

Hi @Outseek. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
Based on the information provided in your question and the knowledge sources available, it appears you're encountering a port-related issue when deploying your Wasp application to Fly.io. Let's address this problem step by step.
1. Port Configuration:
The error message suggests that your app is not listening on the expected address (0.0.0.0:3000). This is a common issue when deploying to Fly.io with Wasp applications.
2. Environment Variable:
One crucial step that might be missing is setting the
PORT environment variable. According to the Wasp deployment docs (https://wasp-lang.dev/docs/advanced/deployment/manually#set-up-a-flyio-app), you should set this variable:
Note that the docs suggest using port 8080, not 3000. This is important because Fly.io expects your application to listen on the port specified by the PORT environment variable.
3. Server Configuration:
In your Wasp application, make sure your server is configured to listen on the port specified by the PORT environment variable, not a hardcoded value like 3000.
4. fly.toml Configuration:
Your fly.toml file seems to be set up correctly with internal_port = 3000. However, this should match the PORT environment variable you set. Consider updating it to:
5. Dockerfile:
If you're using a custom Dockerfile, ensure it's configured to use the PORT environment variable when starting your server.
6. Redeployment:
After making these changes, try redeploying your application:
If you're still encountering issues after these steps, you might want to check the server logs for more detailed error messages:
Remember, Wasp generates the deployment code in the .wasp/build/ directory. You can inspect this code to ensure everything is set up correctly before deployment, as mentioned in the Discord support thread (https://discord.com/channels/686873244791210014/1223671727943319584).
If these steps don't resolve your issue, you may need to provide more information about your specific Wasp application setup and deployment process for further assistance.

Sorry @Outseek, I seem to be having a bit of trouble. Don't worry though, I've pinged my support and they will try to fix me up! :technologist:
Perhaps try again in 15mins?I just followed all of that but still getting this error

@Outseek Could you check if you have log errors in the fly app (server)?
ps: did you set all env vars in the server/client?
@Outseek any way to provide more info? Have you ever before successfuly deployed Wasp app to Fly? What version of Wasp is it?
Did you modify that toml file in any way?
Are there any errors coming from server, on the fly, under logs?
Yes there are errors in the fly logs. I did not modify the toml in any way. I even created a new fly account and tried to get it to work. here are the logs.

TOML file
fly.toml app configuration file generated for basebuddyapp-server on 2024-11-05T21:32:20-05:00
See https://fly.io/docs/reference/configuration/ for information about how to use this file.
#
app = 'basebuddyapp-server'
primary_region = 'mia'
[build]
[http_service]
internal_port = 3000
force_https = true
auto_stop_machines = 'stop'
auto_start_machines = true
min_machines_running = 1
processes = ['app']
[[vm]]
memory = '1gb'
cpu_kind = 'shared'
cpus = 1
and yes I have tried to set PORT=3000 but that has never worked.
Do all of them NEED to be set. Seems like an unrelated issue becuase the sever is not even connected
Also I have never deployed it successfully. Only the client and database work not the server
Well, Idk, Its a possibility
Have you done (?):
#### Server Secrets If your app requires any other server-side environment variables (like social auth secrets), you can set them: 1. initially in thehttps://wasp-lang.dev/docs/advanced/deployment/clilaunchcommand with the--server-secretoption,
or 2. after the app has already been deployed by using thesecrets setcommand:
Deploying with the Wasp CLI | Wasp
Wasp CLI can deploy your full-stack application with only a single command.
If it compiles well in local (it happened to me), when deploying it gave me the same problem as you.
I realized that the port error was because my machine was turned off BECAUSE the Server had crashed and rebooted 10 times and .... why?
Because I left some server variable like Analytics or other, and gave server compilation error, so it crashes and restarted.
Okay and the variables you are reffering to those in the ENV file?
@NEROX
Yes
@Outseek , it is hard for me to say more from this -> is there any chance tehre are more logs coming from the server logs? I believe there should be more.
There is a fair possibility that your server is not running and that is why there is nobody listening on port 3000. Reason for this is often not setting all the env vars, so server is crashing. It is not super easy for me to asnwer what you need, but the answer is normally in the logs. You can look into your .env.server file and see if thre is anything set there but nt in production, that should give you a good idea.
Other than that, what can help is if we can replicate the issue and test it ourselves. For exapmle, you cuold try with simpler wasp app, sometihng basic, and if that also doesn't work, share the code with us and we will giv it a try.
Okay Ill try to set all the env vars and tehn see if that fixes it!
Wohooo @Outseek, you just became a Waspeteer level 1!
