Hello, I'm getting this error. Can you help me with this?

Hi,
Is there anyone who can help with this matter?

Hello @fkeles

Please specify what do you use? It is DocSpace?

I installed it from here: Installing ONLYOFFICE Docs for Debian, Ubuntu, and derivatives

Thanks. Did you integrate Docs (Document Server) with a cloud storage? Please specify the version of Document Server that is being used currently too.

I didn’t integrate it with cloud storage. onlyoffice-documentserver 9.3.1

Do you use integrated test example?
