Help please cant connect to Seahub

Hi, I am new here hope my question will not be too stupid, searched around and could not find a solution.

I have downloaded and installed the windows server from here:

https://manual.seafile.com/deploy_windows/download_and_setup_seafile_windows_server.html

Server appears in the system tray but I cant connect to Seahub.

Seasfserver-applet.log says: SetMenuItemInfoW failed with error 1456

What am I missing?

Many thanks
