problem paying via the cox website

just wondering if anyone else is having issues paying cox bill via the website?? constant "page cannot be displayed" erro when clicking on the view/pay bill link. I was able to get in last Friday, made the payment, got the "thank you for your payment" message, yet right under that another message read, payment unsuccessful. I can remember the detailed message but was to the effect of taking longer then normal, and it's on our end. I didn't receive the confirmation emal, so I tried on Monday again, and after struggling with the page cannot be displayed issue, I was able to go thru the payment process. this time got the message, payment not accepted due to pending payment. tried logging in today and am getting page cannot be displayed and 502 bad gateway messages. the cox site is the ONLY one I ma having issues with. I've treid clearing cache/cookies. is anyone else having issues? was able to get in and see the balance, still there. CC has no pending transactions.
