Server 14 and Desktop Client 15 -- cannot download because encryption information missing

Hi Nextcloud help!

I am using the nextcloud system, and have run into an error. I have both
server-side encryption enabled, and e2e encryption on a folder, we’ll call this
folder F0. A file called “Test.txt” was added to and deleted from F0. I now get the error
“Test.txt cannot be downloaded because encryption information is missing” The same
happens for any folder added to F0, now. Once a folder is encrypted in Nextcloud with
e2e, is there something I am not doing to make everything work out?

I’m sure there is a way to fix this, and any help you can give would be tremendously
