My client has a test site with a test copy of sage 100 2018 Standard with this website working fine there.

When we installed it on the live server and configurated it we are getting HTTP error 503. The Service is unavailable on trying access anything on the IIS website for ebusssiness webservices.

The HTTPS has a self signed cert SSL, but so does the test site/server with no errors.

Screen shot bellow showing test link.   

We tried uninstalling and re-install .Net items from server, uninstalled and re-install Ebussinesss Webservices and IISreset as well as comparing all items in sage 100 for setup of this from working testing environment to non working live environment.
