Thank you for letting us know here. I’d suggest you to also let the site owners know you are encountering issues as well if you could.
Could be you’re using an outdated Web browser version, or TOR, or a VPN possibly?
Are you running any anti-virus software on your device?
If the site owner contacts Cloudflare Support and shares a Ray ID, the Cloudflare Support team could investigate further. If they could share their ticket number too, we could track to understand the issue better. Currently, you haven’t shared an URL of the domain where you’re experiencing an issue, therefrom I am afraid we cannot help further.
