It looks like something is going on from a cache/cookie point of view.
watchoptik.telus.com should only direct to the HTML5 site, and not the Flash site unless the cache isn't being flushed properly. This is likely why Safari isn't working - Apple removed Flash capability a couple of months ahead of the end-of-life.
The URL shouldn't resolved to 'reachclient...' unless you're being redirected to the Flash site.
If you're confident that the cache is clear, I'd recommend re-booting your computer and trying again in private/incognito first, then regular browser.
