"Unable to send message." error

[bmomjian]

I just stated getting an "Unable to send message." error every time I try to chat to a Hangouts group, and all of my non-group hangouts people are showing as offline. Are others seeing this too?

Google has shut off the Hangouts API. You'll need to switch over to the https://github.com/EionRobb/purple-googlechat plugin instead

Worked perfectly on Ubuntu, thank you.

I'm going to be annoying and leave this issue open for other wayward souls who find themselves in the same position :)

@EionRobb,
is this Hangouts API shutdown you're mentioning related with this message that I started getting on the logs a couple of days ago?

hangouts: Error from server: (Invalid HTTP response code (403)) {
  "error": {

      }
    ]
  }
}

If so this is really sad, 2 of the issues that were preventing me to switch to libpurple-googlechats is that occasionally there will be individual messages I won't receive on Pidgin, only on the actual GC app or on gmail (same for the contacts on the other side), and the 2nd problem is that people using Pidgin are not shown on the other side with the "green" status as being present.
