I have recently installed OnlyOffice Community Server and Document Server onto a RHEL 7 server using docker. Everything seems to have been set up correctly. The sample documents open and edit as expected.
However, my use case for the Document Server is editing of large excel files with a lot of vlookups in between columns and sheets. The document I have currently is 45 mb. This document uploads into community server fine, and can download again correctly, but when I try to edit it, I get a message saying unknown error. I'm not really sure where the logs are generated that would show information about the error. Can anyone point me in the correct direction?
