I have a video call app that was published about a month ago. From the moment the application started, the application stopped working - whenever I try to redirect the user to a video call, the answer 404 follows. The same thing happens when I click on the video call link directly under the developers console ( https://hangoutsapi.talkgadget.google .com / hangouts? gid = <MY_ID>). I cannot find any api changes or other tips that indicate the cause of the problem. Any ideas?
I ran into the same problem. I sorted it using the following URL format
https://plus.google.com/hangouts/_/?gid=<Your_ID>
I found that google changed this to https://hangoutsapi.talkgadget.google.com/hangouts/_?authuser=0&gid=
