Because NodeJS uses an hardcoded list of certificates if you deploy a site (receiving the webhook from wekan) behind a reverse proxy on https with a Let's Encrypt certificate you may have a problem: Let's Encrypt's CA is not recognized. The correct answer is here.

• Download the Let’s Encrypt Authority X3 (IdenTrust cross-signed) from here

  cd /etc/ssl/certs
  wget https://letsencrypt.org/certs/lets-encrypt-x3-cross-signed.pem.txt -O lets-encrypt-x3-cross-signed.pem
  

• Now start the application with

  NODE_EXTRA_CA_CERTS=/etc/ssl/certs/lets-encrypt-x3-cross-signed.pem node main.js
