To debug your SVN connection, it is useful to enable logging. Modify the system property while launching the Java VM with:

$java -Djava.util.logging.config.file=path/to/logging.properties.disabled

To do this:
1) Download the logging.properties.disabled file attached to this document.

The logging.properties.disabled file contains a system property svnkit.level used to control the log level:

2) Configure Bamboo to start with the -Djava.util.logging.config.file=*path/to/*logging.properties.disabled command, where "path/to/" refers to the absolute path to the logging.properties.disabled file from step (1).

The method of doing this depends on which operating system you are using:

3) Save your changes, and restart Bamboo for your changes to take effect.

4) You will find the SVNKit log file in USER_HOME/svnkit.0.log (where USER_HOME is the home directory of the user running Bamboo or logged in e.g: /home/user/svnkig.0.log).
