Cannot complete first Time Machine backup on fresh Sequoia install on Time Capsule

[MitzEclipse]

Just did a fresh re-install of Sequoia on a Macbook Air M1. I can connect to the Time Capsule on the same wifi in my house.
I have deleted the disk partition and started clean so I have a completely empty Time Capsule 2TB free.

The backup starts and goes on for 24h - laptop is plugged in and connected. After almost 24h, the backup cannot complete. I have now tried this 3x.

I did a search and previous suggestions was to wipe the disk partition, which I did. Looking for other suggestions please as it's odd I cannot get the backup to complete on a fresh Sequoia build.

Thanks

also to add - I was able to backup successfully to an external SSD HD. I just have the issue with the Time Capsule. I keep getting the attached error - any suggestions?

Original HDD in Time Capsule? Could be HDD is finally failing. Remove from Time Capsule. Using SATA USB adapter or enclosure, attach to your Mac, open Disk Utility and try to run First Aid.

Yes original however backup was working just fine pre sequoia !

Any other ideas? I put the macbook right next to the time capsule to see if wifi range was an issue - still same error. I will try again via ethernet directly to the time capsule

Definitely use Ethernet for the initial backup, if it fails, use T2M2 to view the log: https://eclecticlight.co/consolation-t2m2-and-log-utilities/

While the time capsules were very cool; in there day; they haven't been supported in sometime (more then a decade, i would imagine and as such the firmware of the time capsule more then likely attempts to backup your mac with the AFP protocol; which apple hasn't supported for also an extremely long time. Modern time machine backups use SMBv2 at a minimum and APFS snapshots stored inside of a APFS bundle. I'd recommend that you replace the time capsule with anything by synology. You'll get the same functionality and it will work well.

Currently have over 11TBs of APFS bundled time machine backups on my synology.

Hope that helps.

I'm still backing up my 2018 MBP to a Time Capsule on Sequoia and it's still working, so that's probably not the issue.

You should be able to remove the TC disk from TM destinations and add it back. You won’t lose prior backups but be prompted to adopt them.

Thanks all - I did remove the TC disk and in fact, wiped the whole thing and started again. at first it failed again. I moved the laptop closer to the TC and tried again. Still did not work. Moved it back to my office (where my laptop has full wifi connection and never had an issue with TC range before) and tried yet again and it magically worked. At least the first backup. Now trying again.... still don't know the root cause which worries me but at least it worked!
