OnlyOffice Error on save

Hy,

I have installed filerun on a debian server. I have installed onlyoffice on a clean Debian server that is only accessible as an ip address. The Filerun server is accessed via the web. When I try to edit a page via onlyoffice, the only office plugin loads fine, and the document is loaded, but the save generate an error.

Error in OnlyOffice
