If you've tried to register for the forum, but you get back a 403 error, you may be wondering what you can do to fix the problem. How do you register for the forum?
A 403 error is returned when your IP is reported as “poor” on the Barracuda Black List. You will either need to register with a different IP (which does not have a poor rating on the Barracuda Black List) or request a removal from the list.
We do apologize for this inconvenience, but there is no way for us to whitelist your IP, as our forum software searches against the Barracuda database every time. In fact, a lot of sites and services might use this same blacklist. In order to avoid any issues on other sites as well, it might be best to try to get your IP unlisted.
If you still cannot register on our forum with A different IP, feel free to join our public Slack community and discuss your issue there.
