I am setting up oxd server on a box running nextcloud and using the nextcloud plugin to authenticate users to my gluu server CE as IdP. This is on ubuntu 16.04 on amazon ec2. The install of the package seems to run fine, however, when i go to configure the server with the config file and then start the server, i can't register the nextcloud plugin from the nextcloud interface. It keeps telling me 'Can not connect to the oxd server. Please check the oxd-config.json file to make sure you have entered the correct port and the oxd server is operational.' I have checked the file, checked the port, reinstalled the server, started and stopped the server, used the config files from 3.1 and still nothing, same message. I just went through this with wordpress and it seems to have run fine on that box, but my nextcloud install is giving me a much harder time. The 'oxd-server.log' file shows the following output: 2017-10-28 01:39:13,053 DEBUG [org.xdi.oxd.server.service.SocketService] Start new SocketProcessor... 2017-10-28 01:39:13,053 TRACE [org.xdi.oxd.server.SocketProcessor] Socket processor handling... 2017-10-28 01:39:13,053 TRACE [org.xdi.oxd.common.CoreUtils] commandSize: -1, stringStorage: 2017-10-28 01:39:13,053 TRACE [org.xdi.oxd.common.CoreUtils] Parsed sizeString: 0731, commandSize: 731 2017-10-28 01:39:13,054 TRACE [org.xdi.oxd.common.CoreUtils] Read result: ReadResult{m_command='{"command":"register_site","params":{"op_host":"https://auth.bmwpugetsound.com","authorization_redirect_uri":"http://files.bmwpugetsound.com/index.php/apps/gluusso/loginfromopenid","post_logout_redirect_uri":"http://files.bmwpugetsound.com/index.php/apps/gluusso/logoutfromopenid","application_type":"web","acr_values":[],"scope":["address","profile","mobile_phone","phone","permission","clientinfo","email","user_name","openid"],"client_jwks_uri":"","client_token_endpoint_auth_method":"","client_request_uris":null,"contacts":[""],"grant_types":["authorization_code"],"response_types":["code"],"client_logout_uris":["http://files.bmwpugetsound.com/index.php/apps/gluusso/logoutfromopenid"],"client_id":null,"client_secret":null}}', m_leftString=''} 2017-10-28 01:39:13,054 TRACE [org.xdi.oxd.server.Processor] Command: {"command":"register_site","params":{"op_host":"https://auth.bmwpugetsound.com","authorization_redirect_uri":"http://files.bmwpugetsound.com/index.php/apps/gluusso/loginfromopenid","post_logout_redirect_uri":"http://files.bmwpugetsound.com/index.php/apps/gluusso/logoutfromopenid","application_type":"web","acr_values":[],"scope":["address","profile","mobile_phone","phone","permission","clientinfo","email","user_name","openid"],"client_jwks_uri":"","client_token_endpoint_auth_method":"","client_request_uris":null,"contacts":[""],"grant_types":["authorization_code"],"response_types":["code"],"client_logout_uris":["http://files.bmwpugetsound.com/index.php/apps/gluusso/logoutfromopenid"],"client_id":null,"client_secret":null}} 2017-10-28 01:39:13,060 INFO [org.xdi.oxd.server.op.RegisterSiteOperation] Creating site configuration ... 2017-10-28 01:39:13,060 TRACE [org.xdi.oxd.server.service.HttpService] Created TRUST_ALL client. 2017-10-28 01:39:13,098 ERROR [org.xdi.oxd.server.op.RegisterSiteOperation] ClientId: null, clientSecret: null 2017-10-28 01:39:13,098 ERROR [org.xdi.oxd.server.op.RegisterSiteOperation] Value of one or more redirect_uris is invalid. 2017-10-28 01:39:13,099 ERROR [org.xdi.oxd.server.op.RegisterSiteOperation] Failed to register client for site.
