Hello Community,

i have a Problem with a selfhosted n8n instance over an nginx reverse Proxy.
The Test URL looks good and works perfect. My Production URL is not right, see attached photos.

Can anyone help me ?

Thank you.

N8N_HOST must be the domain only. no protocol. no slashes.
change N8N_HOST to just n8n.your-domain.de.
n8n takes that variable and tries to force its own internal logic on it, which is why you end up with that frankenstein http://https:// url in the dashboard. N8N_HOST is meant to be just the domain string.
keep WEBHOOK_URL as is

you need then to force it to read the new config:

docker compose up -d

run that in your terminal.
