Pandora stopped working recently... auth token issue

Streaming Sources
1

I’m not 100% sure it’s related to the latest update, but after I rebooted once it (0.2.1) was applied, I find that Pandora isn’t streaming anymore.

I ssh in and look around and found this in:

~/amplipi-dev/config/srcs/0/.config/pianobar/output:

pi@amplipi:~/amplipi-dev/config/srcs/0/.config/pianobar $ cat output
Welcome to pianobar (2019.02.14)! Press ? for a list of commands.
(i) Control fifo at /home/pi/amplipi-dev/config/srcs/0/.config/pianobar/ctl opened
(i) Login… Error: Invalid auth token.

Which leads me to:

And I’m not sure what else makes sense to do. Even a reboot doesn’t seem to cure it.

Sorry you are having this issue. We didn’t make any changes to Pandora recently.

At Micronova Pandora is the most used streaming and we don’t recall seeing this exact issue.

We have some hunches as to what could be going wrong though. I listed them below. Do either of these seem plausible?

1. Time Synchronization

Some customers have issues in the past where there time goes out of sync, which would probably cause authentication to fail. Could that be the underlying issue? You can check your AmpliPi’s time over ssh with timedatectl status. Here is what the output should look like.

               Local time: Tue 2023-03-21 10:56:47 EDT
           Universal time: Tue 2023-03-21 14:56:47 UTC
                 RTC time: n/a
                Time zone: America/Detroit (EDT, -0400)
System clock synchronized: yes
              NTP service: active
          RTC in local TZ: no

The main things to verify are Universal time, System clock synchronized, and NTP service.

2. Way too many streams

There is another failure mode that we have seen in our testing, but I am not sure how common it is as we have only experienced it once.

One time we had many many Pandora streams running at once and after an hour or so all of our Pandora streams started failing with a similar error to what you were experiencing however we did not record the error message for posterity.

The fix was to stop using Pandora for the day, the next day everything started working again. Our IP must have gotten on a naughty list for the day.

I hope this helps!

Hmm.

Time looks OK.

pi@amplipi:~/amplipi-dev/config/srcs/0/.config/pianobar $ timedatectl
               Local time: Tue 2023-03-21 11:32:47 EDT
           Universal time: Tue 2023-03-21 15:32:47 UTC
                 RTC time: n/a
                Time zone: America/Detroit (EDT, -0400)
System clock synchronized: yes
              NTP service: active
          RTC in local TZ: no

I guess I’ll give it a day or two and see if it clears up. If it’s the “bad IP” theory, I assume it’d affect any device in our house trying to use Pandora–I’ll check a few others and see if they work.

Thanks,

Jeremy

Thanks for checking!

IIRC the ip block did not effect any normal first party Pandora clients like pandora.com or the android app.
