If you have not tried any troubleshooting please do the following:
- Restart in Safe Mode per the directions in Safe Mode. Then restart normally and test.
- If the Safe Mode restart does not work then I'd recommend running First Aid (Applications - Utilities - Disk Utility - First Aid) on the Time Capsules drive. It is quite old and may have failed. Run First Aid 2-4 times as it does not always find errors on the first pass. If errors occur that means the drive is dead and you need a new Time Machine solution.
You can also try:
- First, click the Apple icon at the top-left corner of the window.
- Next, select the System Preferences option from the drop-down list.
- Choose the Time Machine option from the System Preferences window.
- Click the “Stop using Time Machine for Backup” option.
- Now, go back to your Mac’s main screen and launch the Finder app using the dock at the bottom of the window.
- Select the Applications category from the left menu panel.
- Click on the Utilities option from the list.
- Choose the Keychain Access option.
- Here, search for the NAS hostname and remove all the matching passwords.
- Now, open the Time Machine window and select the Add Backup Disk option.
- Choose Time Machine and enter the NAS login password to update.
