1020 on Open Web Analytics (OWA) - many domains

May I ask if you tried to disable Rocket Loader option at Cloudflare dashboard? :thinking:

Have you checked your directory permissions and group/owner?:

Have you checked your access and error log files at your origin host/server?

Before moving to Cloudflare, was your Website working over HTTPS connection?

May I ask what SSL option have you got selected under the SSL/TLS tab at Cloudflare dashboard for your domain ( Flexible, Full, Full Strict … )?

If these are your websites and you experience 1020, you have to check Firewall tab to troubleshoot and find any clue why it happens.

Are you blocking some countries?

Can you share a screenshot of your Firewall Rules?

Are all the domains on the Free plan or?

I am not familiar with this service, therefore I believe it’s not banned.

Which one is the web app using?
