@DazedDay , there are some things you can try to see if it will resolves this issue. I managed to get back to normal after trying a few different things. Its possible that the IP block I was on was old/bad and should have been refreshed but sometimes the modem/CMTS that feeds it get stuck on the old address. You can check what you current IP is and compare it to the logs on PSO2 and see if the login IP and the current is the same. (IP Chicken is a good site to hit up to see your current IP) If it is, getting a new IP could fix the problem.
Normally rebooting the cable modem will fix it but not always. If rebooting does not work, try factory defaulting the modem. If all else fails, the only other method would be to swap the modem.
Unfortunately there is no process from Spectrum's side to manually refresh the IPs due to how the technology works. About the best they can do is send a signal hit to the modem and try to reboot it remotely.
Hope this helps you. Also the reason I know some of this is because I used to work support when Timewarner Cable was around.
