Local and server files are out of sync but no oss on shared host

Nextcloud version (eg, 10.0.2): 12
Operating system and version (eg, Ubuntu 16.04): 1&1 shared host (linux)
Apache or nginx version (eg, Apache 2.4.25):
PHP version (eg, 5.6): 7
Is this the first time you’ve seen this error?:
Can you reliably replicate it? (If so, please outline steps):
The issue you are facing:
My server and local files are out of sync. I deleted the files on the server but they still exist on the web ui. I cannot use the oss command on 1&1 shared host.

Please help. What are my options?

Limited. I don’t believe it will update automatically if you’re deleting data directly out of the data folder (hint: don’t do this).
