- An alternative would be to use letsencrypt.  If you are using a reverse proxy, usually nginx-proxy,
+In the Chromium broswer: chrome://settings/certificates

+- LETSENCRYPT
+ A preferable alternative would be to use letsencrypt.  If you are using a reverse proxy, usually nginx-proxy,
  make certain that HTTP_X_FORWARDED_FOR is used for identifying the originating IP address, 
  because YBDB shops keep track of their unique ip.
