i run a owncloud client 2.2.2 on ubuntu 14.04. The Server runs owncloud 9.1.0
On my local client, I get a "no connection, timout"-message.
Two things could be connected with the problem: - login with ssh on the owncloud-server is very slow due to unknown reasons - the certificate of the server is not registered. In firefox I have to add it manually to a list of allowed certificates
Over years this owncloud-setup was stable, using 8.0.3 on the Server, and pre-2.0 as local client.
But calling the page directy in the browser is quick enough. it loads in around 5 seconds, including authentication. ssh needs about two minutes to connect, but behaves normal afterwards.
