Hello,

Your backend domain returns a 502, for this error, please see this docs page -

https://docs.railway.com/reference/errors/application-failed-to-respond

Best,
Brody

I've tried changing it to everything possible and it doesn't work...I don't know what to do and I've already seen that doc.

I've added my domain (from OVH) and changed the environment variables and now I have:
Failed to load resource: the server responded with a status of 404 ()

Client-side error: Error during signup

Any ideas on how to solve this?

Hello,

I followed the docs and applied the needed changes, and your backend service domain now works.

Best,
Brody

Hi,

What have you done exactly?
We were fixing with my husband (much more senior than me).
Thanks,
Rita

I set the target port correctly -

https://docs.railway.com/reference/errors/application-failed-to-respond#target-port-set-to-the-incorrect-value

The port on backend has disappeared...?
Have you inserted something else or just removed it?
It's not working...404 still.

Please see the docs page I linked, it shows what I changed and where I changed it.

As for the 404, you are liking calling your frontend domain to do the login when you need to call the backend domain.

And please know that you are running a development server for your frontend.

https://github.com/brody192/create-react-app-starter

Copy the nixpacks.toml and Caddyfile from this repo into your repo to run a production grade web server.

I've changed the port to 443 meanwhile on the frontend.

All the variables are using https://www.hrnov.ai.

I have copied the two files in my repo at the root of it.

Am I supposed to change anything in them?

https://www.hrnov.ai is the frontend domain, your sign-in needs to call the backend domain.

You don't need to change anything in the Caddyfile and Nixpacks.toml files, so please push those changes.

Do I need to change the variables?

Your frontend needs to call the backend domain for the sign in, that's all the advice I can provide as I do not know what or how you use environment variables in code.

Please remove the start command from your frontend's service settings.

I understand, bit lost...this is my first deployment

Example of the signup below.

API_URL is linked to an environment variable that calls: localhost 4000.

Do we agree on this case that it should be the backend url?

  const handleSubmit = async (e) => {
    e.preventDefault();
    if (!validateForm()) return;

    const requestBody = {
      firstName: formData.firstName,
      lastName: formData.lastName,
      email: formData.email,
      password: formData.password,
      role: userType === "company" ? "company" : "candidate",
      companyName: userType === "company" ? formData.companyName : undefined,
    };

    try {
      const response = await fetch(`${API_URL}/signup`, {
        method: "POST",
        headers: { 
          "Content-Type": "application/json",
        },
        body: JSON.stringify(requestBody),
        credentials: "include",
      });

      if (!response.ok) {
        const errorData = await response.json();
        throw new Error(errorData.message || "Error during signup");
      }

      const data = await response.json();

Your REACT_APP_API_URL is set to the frontend domain, I've changed it to point to the backend domain.

That change is a part of your staged change.

Ok, there's 5 changes on Frontend side.

Anything else to change or is it good to go like this?
(thanks for your patience, you're my savior)

I think it should be good.

There's a Failed to load resource: the server responded with a status of 500 ()
Is there a problem with the server?

500 would be a code issue on your backend.

Have you looked at your deploy logs for the backend? you are trying to connect to postgres at 127.0.0.1:5432

You should be connecting by using the DATABASE_URL variable.

As PG_URL, I have ${{Postgres.DATABASE_URL}}.

AS DB_HOST: postgres.railway.internal

etc.

Don't see where I have that...

You would want to use the DATABASE_URL and only that variable in your code to connect to the database.

None of these?

DB_HOST

DB_NAME

DB_PASS

DB_PORT

DB_USER

Nope, That's just extra complications, using a single variable is the best path forward.

Ok, just changed and redeployed.

Your code is still trying to connect to 127.0.0.1:5432 for postgres.

It's redeploying and building.

It's now working!

Thank you sooooo much for your help.
Without you, I would still be screaming to my screen (lo).

Ok now I have:
TalexaSubscription.jsx:173

GET https://backend-production-717e.up.railway.app/api/subscriptions/user/current 401 (Unauthorized)

POST https://backend-production-717e.up.railway.app/api/subscription/session 401 (Unauthorized)
When I try to add a subscription to pay it.

Unfortunately that's a code issue that we couldn't provide help with, but when in doubt check the deploy logs for more information!

Sure, thanks
