n8n errors / Connectivity

self signed certificate

platform: n8n / category: Connectivity / code: DEPTH_ZERO_SELF_SIGNED_CERT

Cause

The target HTTPS endpoint presents a self-signed certificate that n8n's Node TLS layer rejects because it is not in a trusted CA chain.

Fix

In the HTTP Request node Options, toggle on 'Ignore SSL Issues'. For nodes lacking that option, set NODE_TLS_REJECT_UNAUTHORIZED=0 as a temporary, private-network-only workaround. For a proper fix, point NODE_EXTRA_CA_CERTS (or SSL_CERT_FILE) at your internal CA bundle.
