OOS on-prem Excel Online Autosave

Hello Everyone,

We are deploying Office Online Server on-prem integrated with NextCloud Storage everything is working as expected but Excel autosave is not working at all, even when trying to save-as manually it is stuck at "working on it" Below are logs from the server. Any help would be appreciated.
