In OpenTok, why do I get "token passed is invalid" and "session failed to connect"

I couldn't get the quickstart code to work on my site so I inserted a line of debug code (TB.setLogLevel(TB.DEBUG);) to see where it was tripping up. It failed saying 'The token is invalid'. Here's the debug outputs- I xx'ed out my unique IDs for privacy but they match what I was given. Any idea why it's failing?

Solution

One possible reason for this error is that your token is invalid. This could be because:

The token has expired.
The token was generated for a different session id than the one you are using.

For either case, try generating another token for the session and using it in your code.

Good luck!
