Hi, all. Pardon my inexperience. The error seems a bit basic, but I haven't been able to figure out the issue. I have a website I would like redirected from OpenResty NGINX (using lua-resty-idc) to Gluu for authentication, then to the website (if auth is successful). `OpenResty NGINX --> Gluu (SSO) --> Website` ```` OpenResty NGINX: 192.168.10.100 Gluu (SSO): 192.168.20.100 Website: 192.168.30.101 (https, port 5001) ```` I followed this tutorial here: https://gluu.org/docs/ce/integration/sswebapps/nginx/ On my network's DNS server, I set a host override so that my website (192.168.30.101) points to my OpenResty NGINX server (192.168.10.100). Upon going to https://website.example.com, I get the following error: ```` **Error:** "invalid_request_redirect_uri" **Error Description:** "The redirect_uri in the Authorization Request does not match any of the Client's pre-registered redirect_uris." ```` My URL also redirects to: `https://sso.example.com/oxauth/restv1/authorize?response_type=code&client_id=XXXXXXXX-XXXX-XXXX-XXXX-376fd0cfa7c9&state=61cd2dedd7e320d3cdb60c0792627fca&redirect_uri=https%3A%2F%2Fwebsite.example.com&nonce=9483ca80db11b98fdf1e932b9e569079&scope=openid%20email%20profile` Pictures of OpenResty NGINX config, client summary, and sector identifier summary: https://imgur.com/a/2ndhimy FYI, when manually going to https://192.168.30.101:5001, page displays just fine (with self signed cert error, of course). Please let me know if there are any particular logs you might need.
