The jwks endpoint does not allow an Accept header of "application/json", an HTTP 406 response is returned. Fails: curl -k -H "Accept: application/json" https://seed.gluu.org/oxauth/seam/resource/restv1/oxauth/jwks Response: ``` <html><head><title>Apache Tomcat/7.0.55 - Error report</title><style><!--H1 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:22px;} H2 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:16px;} H3 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:14px;} BODY {font-family:Tahoma,Arial,sans-serif;color:black;background-color:white;} B {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;} P {font-family:Tahoma,Arial,sans-serif;background:white;color:black;font-size:12px;}A {color : black;}A.name {color : black;}HR {color : #525D76;}--></style> </head><body><h1>HTTP Status 406 - No match for accept header</h1><HR size="1" noshade="noshade"><p><b>type</b> Status report</p><p><b>message</b> <u>No match for accept header</u></p><p><b>description</b> <u>The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers.</u></p><HR size="1" noshade="noshade"><h3>Apache Tomcat/7.0.55</h3></body></html> ``` Works: curl -k -H "Accept: */*" https://seed.gluu.org/oxauth/seam/resource/restv1/oxauth/jwks Installed Gluu CE on a Centos 6 server using the instructions found here -- http://www.gluu.org/docs/admin-guide/deployment/centos/ Please let me know if you need any more information.

Aaron, The hostname should be your Gluu Server's hostname than 'seed.gluu.org'. You can grab the openid connect configuration with `https://<hostname>/.well-known/openid-configuration` If you still get error, tail wrapper.log and post stack trace of error.

This is not related to the error you are getting. This stack trace is about ssl_checker, not related to the issue you are facing.

Mohib, Oops, you are right. There actually isn't an error/exception in gluu thrown since the jwks service is only configured to accept "text/plain". That is why we get the "HTTP Status 406 - No match for accept header" response from gluu. See -- https://github.com/GluuFederation/oxAuth/blob/master/Server/src/main/java/org/xdi/oxauth/jwk/ws/rs/JwkRestWebService.java Line 51 has: @Produces({MediaType.TEXT_PLAIN}) Do you think it would make sense to allow 'application/jwk json' in addition to 'text/plain'? The reason behind the 'application/jwk json' comes from -- https://tools.ietf.org/html/rfc7517#section-8.5.1 Thanks again, Aaron
