We are temporarily unable to process your request

I haven't used my iTunes account for some time. However, I recently purchased an MP3 player for listening to music/podcasts for sports. I have a decent library of music from my iTunes account. I have been unable to access it. I was able to login to my account. But unable to authorize a new device to access the previously purchased songs. When I attempted to authorize the device via "Account" and Authorize this device in apple music/iTunes, it simply stated "We are temporarily unable to process your request. Try again later."

Any suggestions?
