I have the same issue. I confirmed its IP based. If i loging to another ISP im fine. I kept refreshing the pearson vue page to see if the time i wanted for an exam someone dropped to become available. So i guess in doing so PeasonVue thought i was a bot. Now i have the exact seem issue as TheBMAN33 stated.
The Captcha repeats endlessly.
I have tried multiple different browers, and clearing the cache in each one. I've also confirmed with my ISP that they are not blocking anything on their end. I never had an issue with this until yesterday.
There has to be a way around this because now that someone else has the same identical issue that flags a serious problem for test takers.
