Didn't have any problems connecting when I just tested, What I would try doing first is to power-cycle your router by unplugging the power cable for your modem / router and leave it unplugged for a few minutes then reconnect and try again.

Try checking your firewall rules, as installing the PTR may have miss-configured the set rules should you have any.
