Request failed with status code 401

Describe the issue/error/question

After deploying n8n to Heroku using the click to deploy button on the eco tier for the web app I’m consistently getting the following error: Request failed with status code 401.

It continuously redirects to the “set up an owner” page, when I fill it out the workflows page just keeps on loading, when I do manage to add a workflow, the workflow gets lost and it redirects back to the “set up an owner” page. n8n is totally unusable at this stage.

I have while debugging downgraded n8n to version 0.184.0 and I’m still getting similar behavior so versioning is ruled out.

I suspect it might be database related but I am not sure. If someone could please assist that would be much appreciated.

What is the error message (if any)?

Hey @JD_Oberholster,

Welcome to the community :tada:

Is there anything in the Heroku logs? It sounds like it could be a configuration thing but it is hard to say.

Hi @Jon

Thanks for the welcome, I love n8n it’s a great product.

Please see the logs below from Heroku.

Hey @JD_Oberholster,

Was there anything else? I will run through the deployment guide and the docs in about an hour or so to see if I can spot anything.

Hi @Jon

There was nothing that stood out in the logs. The DB is looking strange though, you can see in the screenshot below, no tables or rows in the db.

I have checked the database config and the URL matches the URL in the config.

Hey @JD_Oberholster,

Just ran through it, It seems to deploy and work without issues for me at the moment but I suspect as there are missing env options to make Postgres work there will be other issues like if the instance restarts you would need to fill out the information again as the data is normally persisted in the database.

As a temporary solution if you remove…


From the Environment Options then added…

DB_TYPE - postgresdb

In DATABASE_URL the format is…

postgres://USER:[email protected]:PORT/DATABASE

This should at least help you up and running.

Hi @Jon

This worked perfectly. I can’t thank you enough. You have made my day.

Marking this as the solution.

Warm Regards
JD Oberholster

Hey @JD_Oberholster,

I am just working on a new deployment update that should work out the extra bits, I will let you know when it is ready if you wanted to give that a test.

Hey @JD_Oberholster,

If you are interested there is a version here: GitHub - n8n-io/n8n-heroku at fix/database-args which will automatically work out the database settings as well as disable basic auth by default to make life a bit easier.

I have done a few test runs with it now and it appears to be working well so I will probably get a PR put together in the morning but figured I would let you know just incase you wanted to give it a test on a new instance.

Hey @Jon

Thanks a lot. I am going to do another installation this month and will use this version.

Appreciate the efforts!
