I received this error when doing 'svn update': svn: E170013: Unable to connect to a repository at URL …
I spent many minutes trying to find why the perfectly working server would not grant a connection. The solution was: for years in my TortoiseSVN settings a proxy server was selected, and it simply has been working until it happened to be turned off. So I ask for one of two features: A) When "unable to connect to a server", make an extra check whether it is possible to connect to the proxy server (if one is selected). If this is the case, make the error more verbose, like: svn: E170013: Unable to connect to a repository at URL …, also unable to connect to a proxy … B) Simply make the error message more verbose if the proxy server is selected in the settings, like: svn: E170013: Unable to connect to a repository at URL … (Note: proxy … was used for connection)
