There may be a problem with re-using that particular URL and port value, as when the internal web server starts up, there is a random port search that takes place by default, looking for an available port. Depending upon the R session characteristics, port 12300 may no longer be the correct value and thus will fail anyway.

Jonathon, when you checked your browser configuration, did you add 127.0.0.1 to the exception settings anyway?  I don't recall if that would help or not, if a proxy is not otherwise defined.

The alternative would presumably be a Windows or third party firewall configuration setting that is precluding the connection, either to the IP address or to the ports being used.

HTH,
