Set cookies only for exact host

[markus656]

Describe the problem/error/question

I run n8n on a subdomain. When I log in to n8n, various cookies are set.

• rl_anonymous_id
• rl_page_init_referrer
• rl_page_init_referring_domain
• rl_session
• ph_phc_4UR*
• rl_trait
• rl_user_id
• n8n-auth

When I look in the developer tools of my browser to see which domains the cookies are set for, I see the following:

• n8n-auth is set for n8n.example.com
• all others are set for example.com

What is the error message (if any)?

I have other services running under other subdomains, which sometimes interfere with the cookies. Can I change the scope of the cookies somewhere so that they are all set for n8n.example.com only, or is this expected behaviour?

I have already set the following configuration, but this has no effect on this:

    environment:
      - WEBHOOK_URL=https://n8n.example.com/
      - N8N_HOST=n8n.example.com

Hi @markus656

Thanks for posting here and welcome to the community!

This is expected behaviour and you cannot modify these cookies - only disable them by setting N8N_DIAGNOSTICS_ENABLED to false.

You can find more about our telemetry tracking in our docs

Hope this helps!
