Older browsers not supported
Clipstream conforms to the HTML5 standard. Older browsers such as IE8, IE10 and below do not support the HTML5 standard and require a fallback solution such as embedding a Flash player embed in a <noscript></noscript> tag. See Clipstream Player and Clipstream Host Basic Requirements.
Https:// http:// mismatch
If your domain is https:// you must adjust the embed code so that the links also match https://.
Network port blocked
The local network may be blocking one of four common ports that the player attempts to access. These are: 8080, 80, 1234 and 443 (for https:// links). Please contact your network administrator to get these unblocked.
