Updated the site using the crossdomain script but still getting operator disconnect errors. The crossdomain script does not show visitors in the operator panel, maybe because all of the sites are hosted on the intranet (internal domains are all *.web.company.com).

 

Support-Image-Button.js.aspx alone causes disconnects and 503 shutdown of the application when loading 10-20 pages simultaneously.

 

Setting "Network Error Timeout" to 900 did not fix the disconnect error.
