For some reason I am unable to log on to https://www.hogwarts.io/ I have been able to get onto the site since I signed up for it and now today I keep getting MOZILLA_PKIX_ERROR_KEY_PINNING_FAILURE. Is there anyway to have this problem fixed so that I may be able to go back on to the site? I can get onto it using chrome, but I prefer using Firefox.

Hi, please try to rename/remove SiteSecurityServiceState.txt in the Firefox profile folder with Firefox closed.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

Please let us know if this solved your issue or if need further assistance.
