Hello, I’m rather new to pydio - previously I was using pydio server and now it is cells. I have a question, when I’m trying to upload some files - for example .avi or .tar.gz I’m getting error with signature. What can I do to resolve issue of signature ? ---

Hello @dominbdg , Could you give a me a description of your setup, (reverse proxy, server,…) it would help me understand and reproduce your issue. Also would you mind sharing the logs that display the error (make sure to hide sensitive info). ---
