I am trying to install cells-sync on Ubnutu 20.04. I have downloaded it from [https://pyd.io/en/get-pydio/downloads/pydiosync-desktop-app](https://pyd.io/en/get-pydio/downloads/pydiosync-desktop-app), I followed all the instructions there but I cannot get it to work.

It does not connect to the server. I have installed it on a windows machine and it works perfectly so I know that the server is working and it is configured correctly. I get this message when I try to connect cell-sync to my server it takes me to my web browser and says Disconnected application is not yet connected, please wait. I try some commands like ./cells-sync webview , ./cells-sync systray and it shows me the same message.

I would appreciate any help to solve this problem.

Many thanks.

Hello @Manuel_Giraldo and welcome.

is your server behind a reverse proxy? Could you give details about you server setup?
