404 error with non-standard port

I was trying to schedule a build with the schedule build plugin, but got a 404 error. After looking into it, I realized that the plugin was attempting to use port 80 for the build URL, but I am running my tomcat instance on port 8080. After correcting the URL to insert :8080 I was able to schedule the job as desired, although it did not redirect me to the jenkins site after doing so.
