Problems Connecting

I get an error IO Error: Broken pipe

There was a problem with the unerlying network stream either because the connection was too slow or the server wouldn't give a response anymore. Often this is caused when you run out of quota on the server - meaning that your user account is not allowed to use any more harddisk space.

I get an error IO Error: Read Timed Out

When attempting to open a connection, there is either a firewall blocking requests, or no server is listening at the given address and port. If you get this error while already connected to the server, the network connection to the server is too slow or has a too high latency. You can try to increase the connection timout in Preferences → Connection → Timeouts.
