unable to connect to SVN repository via file:///

[Rusty Rusty]

In attempting to migrate fisheye to a new host I receive errors similar to the following for each of the repositories defined within fisheye.   This is fisheye 4.5.3 on CentOS7.  I had originally attempted 4.7.0, received the same errors and reverted to 4.5.3 to match the old server.

Repository paused due to error com.cenqua.fisheye.config.ConfigException: Could not access file:///sprj/svn1/bsi/ : java.lang.IllegalStateException: Can't overwrite cause with org.tmatesoft.svn.core.SVNException: svn: E180001: Unable to open repository 'file:///sprj/svn1/bsi' svn: E180001: Unable to connect to a repository at URL 'file:///sprj/svn1/bsi' svn: E180001: Unable to open repository 'file:///sprj/svn1/bsi' com.cenqua.fisheye.rep.RepositoryClientException: java.lang.IllegalStateException: Can't overwrite cause with org.tmatesoft.svn.core.SVNException: svn: E180001: Unable to open repository 'file:///sprj/svn1/bsi' svn: E180001: Unable to connect to a repository at URL 'file:///sprj/svn1/bsi' svn: E180001: Unable to open repository 'file:///sprj/svn1/bsi' java.lang.IllegalStateException: Can't overwrite cause with org.tmatesoft.svn.core.SVNException: svn: E180001: Unable to open repository 'file:///sprj/svn1/bsi' svn: E180001: Unable to connect to a repository at URL 'file:///sprj/svn1/bsi' svn: E180001: Unable to open repository 'file:///sprj/svn1/bsi' org.apache.subversion.javahl.ClientException: svn: E180001: Unable to open repository 'file:///sprj/svn1/bsi' svn: E180001: Unable to connect to a repository at URL 'file:///sprj/svn1/bsi' svn: E180001: Unable to open repository 'file:///sprj/svn1/bsi'

Is there a particular port that needs to be open to allow access via the file:/// URI?
