400 Bad Request

I am currently running HA 11.3 on a raspberry pi 4. I am working on migrating it to a debian bullseye 11.5. I was able to install the supervised version onto debian and now I am trying to upload a snapshot so I can get this one to match the one on the raspberry pi 4 that I am replacing. Every time I go to upload the snapshot, it immediately says 400 bad request. I have the backup saved to the machine that the HA is sitting on. So the HA and the snapshot are all on the same machine. The backup is 137.9MB. I cannot find anything addressing this issue specifically. Thanks for all your help.
