To be fair, the URL is included, which does reference a TTML resource (http://www.instant-singlica.asia/video/IE11Video/PM_karaoke_07012014_2.ttml)

I agree though that platform and browser are necessary to resolve the question. Having said that, the TTWG can't typically troubleshoot questions about browser implementations, so it may be a question better put to the vendor of whichever browser you are using. One hint might be that the URL includes the text "IE11Video", so it might be worth seeing if it works on IE11 initially.

You can find the TTML W3C Recommendation which specifies document conformance and processor behaviour at http://www.w3.org/TR/ttml1/ for further details of MIME type for example. There's also a validator service for checking TTML documents – I believe the current URL at which this can (perhaps temporarily) be found is http://www.skynav.com:8080/ttv/verify – having just run it against the TTML file it appears that there's content in the prologue, which isn't permitted – perhaps a space character has found its way into the beginning of the file?

No, we can't explain. Because you don't provide any details. Like what platform, what browser, what server, what content (page), what TTML resource, etc. We can't read your mind.

Good day people. Can someone explain why this subtitles in ttml format works
off-line (in private browsing) but not on-line. Are there any restictions (like server
must be located in US or on server must be set MIME type for ttml format or what)?

Thanky you for any answer.
kind regards, nino
