Library problem

Hi all I subscribed to a new set of modules yesterday and opened Rack expecting to see the little red dot but it didn’t appear, and I also can’t see some modules that I know I have installed - the VCV MIDI modules for example. Also some modules aren’t drawing correctly, knobs and buttons are missing. So I logged out of the Library and tried to log in again but I get a message “No response from server”. I’m running 1.1.6 in Ubuntu Studio and everything was lovely until yesterday! My internet connection is fine. Anyone got any suggestions? Thanks
