Thanks Dan. My model wasn’t available for you because I’ve changed its name temporarily, now it is online again.

A couple of days before, I tried different models within the same servers and had no problem with CODAP showing them. That’s why I thought that the secure thing was something new on CODAP (I saw that even I use “http”, CODAP turns it into “https” also adding a “?lang=en” string at the end of the filename, try yourself if you want)

The good news is that I modified my model code based on your directions and then hosted my file on GitHub (which is a secure server) and my model is working fine with CODAP!!

See screenshot attached.

Thanks a lot again!!
