It looks like your connection to our service is very poor. With a ping of 50ms and 0.908Mbps, you are well below the boundaries for being able to start a stream. There were also some stream tests shortly before you tried to play a game that also failed.
But before this, back in 2015, you were able to play successfully with a good connection.
It looks like you moved and/or got a new internet provider, and this has caused you to have a connection that is not solid or fast enough to start a stream with PS Now servers.
Have you moved or changed providers during this time period?
Who is your ISP?
As well, has there been any activity from them in the last year that would include network changes or upgrades?
Sometimes when ISPs change the way their networks work, they reroute connections through areas that cause the ping to our servers to increase considerably, but we have been able to work with them in the past.
If this is the case, we can contact them and see if this can be resolved.
It looks like you used to be connected via Time Warner Cable back in 2015. I am not sure if AT&T used to have a deal with them, and forced you to change to a slower internet, but that is only one facotor.
Other than that, it also looks like you are using Wifi to do this, which is causing a large fluctuation in quality during the connection test (on launch). Can you try connecting to your router physically, to see if this addresses the issue?
We are also seeing users in your area with AT&T U-Verse who are able to stream successfully, but it is likely they have a more solid connection between their router and streaming device.
