The Mendix Modeler contains a version control system that supports collaborating with team members. This document presents fixes that can be used when version control problems arise.

2 Known Problems & Fixes

Below is a list of known problems and steps to fix them.

2.1 Getting an Error Containing SharpSvn.SvnAuthenticationException: Proxy authentication failed

Error dialog with proxy authentication failed

This error means that the Modeler has problems reaching the version control server because of a proxy server.

The proxy settings can be changed in the Modeler by selecting Edit > Preferences and then the Advanced tab. In the Proxy server section, you can change the proxy authentication settings. Fill in the correct User name and Password for the proxy server.
