Self-hosted (Dokploy): Google Calendar auth incorrectly redirects to localhost:3000

[MirzaHamzaUmer]

Hello,

I am running a self-hosted instance of the platform on my own VPS, deployed and managed using Dokploy. My instance is running on a custom domain (https://apse1.pa.email.useprivate.ai).

I am trying to integrate Google Calendar. After I successfully authenticate with Google, the application server incorrectly redirects my browser to a localhost:3000 address, which fails.

Steps to Reproduce:

1. Go to the Calendar integration settings on a self-hosted instance (managed by Dokploy).
2. Click to add a Google Calendar.
3. Sign in with Google (authentication is successful).
4. After Google redirects back to the server, the server then incorrectly redirects the browser to a localhost URL.

Expected Behavior:
The app should redirect back to my production domain (e.g., https://apse1.pa.email.useprivate.ai/calendars).

Actual Behavior:
My browser is redirected to the following URL, which fails:
https://localhost:3000/cmh05tt43000bl70swpnin53q/calendars?error=connection_failed

This seems to be caused by missing or incorrect environment variables for the application's public URL. The app is likely defaulting to localhost:3000 instead of using its public-facing domain.

Thank You

Set the build-time environment variable in your Dokploy configuration:
NEXT_PUBLIC_BASE_URL=https://apse1.pa.email.useprivate.ai

Rebuild your application - this is crucial! The variable needs to be embedded during the build process.

Also configure your Google OAuth settings in the Google Cloud Console:
Add https://apse1.pa.email.useprivate.ai/api/google/calendar/callback to your authorized redirect URIs
Add https://apse1.pa.email.useprivate.ai/api/google/linking/callback if you haven't already (for Gmail authentication)

That's from Cursor. Does this help you or not?

@MirzaHamzaUmer can you please share the docker compose you are using in Dokploy?
I have been trying to deploy inbox zero with dokploy too but i could not figure out how yet.
Thanks in advance :)
