google hangouts msg box can't show on safari

I see the transparent, ghost chat message box too, but then when I try a few minutes, hours or day later, it works. Sometimes there is a Google error message that accompanies it, something like "an error has occurred." Other times, the chat works with one person consistently, then when I try messaging another, that one fails. Odd. This did not occur prior to the switch to Hangouts.

We're seeing this as well. This is happening in Safari and Firefox (latest versions) started happening maybe 2 days ago give or take? I suspect this may be an issue on Google's end since it's effecting two other browsers and only started recently (the latest versions of Firefox and Safari have been out more than 2 days that I'm aware of).

@bpavlov i just installed Firefox 45.0.2, i didn't see this issue reoccured. i think i might be happening only on Safari

Looks like the issue is gone for me.

OS X 10.11.4 + Safari 9.1

edit: It's back!

@Aziz it's an intermittent issue. it happens from time to time.

@Dalmatian Not only is the issue intermittent but also hard to reproduce. I've seen it personally in Firefox this week multiple times (even yesterday) and I've had others report it using Safari and Google Chrome.

I saw it once in Chrome so I restarted the browser and it was fixed. I thought it was a fluke. Chrome 50 just came out.
