May 08 11:23:51 ValidationError: The 'X-Forwarded-For' header is set but the Express 'trust proxy' setting is false (default). This could indicate a misconfiguration which would prevent express-rate-limit from accurately identifying users. See https://express-rate-limit.github.io/ERR_ERL_UNEXPECTED_X_FORWARDED_FOR/ for more information.

It looks like adding export N8N_PROXY_HOPS=1 to env, solved the problem. I did this from https://community.n8n.io/t/x-forwarded-for-header-is-set-but-the-express-trust-proxy-s/51208/7
