Pandora radio stopped working on my denon 1713

Are you able to login? If you can login but you were logged out it may just be a minor glitch/security feature. Put it this way. I have an Instagram account and they log me out periodically. No one else goes on my account, no one reads my messages, and no one posts anything but me.

On the Denon website they had a similiar complaint about Spotify. They suggested rebooting the receiver by unplugging it and then plugging it back in..
Have you made any changes to your router or modem? They may need a software update.

Pandora accounts follow the account, not the device, so you will be able to use your Pandora account on any computer or device you own.
Choose the device you are using below for instructions:
Computer
iOS
Android

You can either write Pandora to get your user ID/password reset, or create another account based on music that you like.

It's probably nothing to do with the laptop. It sounds to me this is a login issue. Go to Pandora's website and try logging in with the Email address and password you originally set the account up with.

Ensure that you have the correct user name and password. If you forget your username have oovoo send your the credentials using the "the forgot password". If that does not work not create a new account and just add your friends and family on the new account.

Check the Denon website. There is a notice for Pandora users. Pandora changed something and Denon products are blocked as of 11/30. They state that they are working on a fix and to check back after 12/6 for the update.

Are you sure your password was with all lowercase letters? Are you sure that as you type each keystroke registers on the screen? Watch the screen as you type your password slowly and make sure it moves with each keystroke. A bad keyboard will cause a problem with your password. If all the above does not solve it turn off your computer, then turn it on and hit the F8 key repeatedly until you see an option that allows you to log into Safe Mode. Take the Safe Mode Option and when it boots up hopefully and depending on your operating system it will give you a log in for the Administrator and for the user which you forgot the password. Log in as the Administrator and hopefully you have not password protected it. Once you log in successfully go to Start/Control Panel/User Accounts. Once you are in User Accounts, select the user account that you forgot the password for and select the option to Remove Password. Then restart your computer.
