I’ve recently started getting the following error message when attempting to access our SVN repository from my Mac, both from the svn command line interface as well as via NetBeans.

svn: E175002: OPTIONS of 'http://svn.company.com/svn/Frameworks/': Could not read status line: connection was closed by server (http://svn.company.com)

After some research, it appears that the Cisco Anywhere VPN client’s Web Security module can interfere with SVN clients.

The solution is to uninstall the Web Security module of the Anywhere client.

/opt/cisco/anyconnect/bin/websecurity_uninstall.sh

After uninstalling the module both NetBeans and the command line client are able to connect to the svn repository as expected.

I hope this helps someone out there who may be encountering a similar issue.
