- Change N8N_HOST to 0.0.0.0 (internal bind address, not domain)
- Simplify VHost extraHeaders to ONLY set Origin header
- Remove duplicate X-Forwarded-* headers (OLS adds these automatically)
- Remove N8N_ALLOWED_ORIGINS and N8N_ALLOW_CONNECTIONS_FROM (not needed)
The key issue was duplicate X-Forwarded-Host headers. OpenLiteSpeed proxy
contexts automatically add X-Forwarded-* headers, so explicitly setting
them creates duplicates that cause n8n validation to fail.
Only the Origin header needs explicit configuration in extraHeaders.
This works with the patched OLS binary (MD5: b9c65aa2563778975d0d2361494e9d31)
that forwards Origin headers from the client.
