When there is a redirect from Jitsi to Jitsi-Keycloak on port 3000 error ERR_SSL_PROTOCOL_ERROR If you move Jitsi Keycloak to a separate host, http://kck.urd-jitsi-vks1.jitsimeethost.com:3000 authorization on keycloack passes but then an error Access to XMLHttpRequest at 'https://keycloak-int-test.jitsimeethost.com/auth/realms/office/account' from origin 'http://kck.urd-jitsi-vks1.jitsimeethost.com:3000/' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource
