I have successfully setup Cloudflare Access with the Gsuite SSO option. I also have an access policy created whitelisting my email address. I use an ZTE wireless/wired router and have configured a DDNS service in its settings for which I have added a subdomain A-record in Cloudflare (proxied/orange setting). It works to access the subdomain and Cloudflare Access login screen shows, SSO works and upon loading the Router login screen, I am dealt a 522 cloudflare error page.
Do I need to upload my cloudflare Origin ceriticate to my router admin settings page for the access to work?
