That's easy to fix. It can happen if there is a change to your network, even something as insignificant as a momentary power failure that causes your network to go offline may cause Time Machine to "forget" where its backup disk is. You just have to remind it.

The following technique can be used to "reconnect" to the backup disk. It will not affect the existing backup history in any way.
Open Time Machine's Preferences and de-select the Back Up Automatically checkbox. Make sure no backups are in progress, otherwise you should wait for it to finish or terminate.
Then, click the "Select Disk..." button, select the backup disk, then Remove Disk, then Stop Using This Disk.
This will not affect any existing backups.
Then, Select Disk... again in Time Machine's Preferences. Re-select the same one under Available Disks, then Use Disk.
"Waiting to complete first backup" will appear, which means it won't do anything until the next scheduled backup. Despite the implication of that message, it does not mean it needs to create a completely new backup, as if it's creating a brand new one. Your existing backups will still be available.
A Notification may appear if your source volume is encrypted and the backup volume is not. That's normal.
Re-select Back Up Automatically. The "Preparing Backup..." status message will remain for a long time. Eventually, "Backing up xxx of yyy" will appear, but those values will not be accurate, nor will the "Estimated time remaining" in Time Machine's Preferences. Just ignore it. It may take a few hours even if your Mac is not allowed to sleep. Time Machine will also pause or become slow if you use your Mac for tasks it considers a higher priority.

It says Time Machine couldn’t complete the backup to “Maureen Hannon’s Time Capsule.local.
The backup disk could not be found.
it was fine until I updated it around 36+ days ago
