Hello. I just did test same with your environment and I got success working. All your configuration seems good except the "zeppelin.server.allowed.origins" config. Can you try to set the "zeppelin.server.allowed.origins" value to "*" like the following?
*# conf/zeppelin-site.xml* *<property>* * <name>zeppelin.server.allowed.origins</name>* * <value>*</value>* * <description>Allowed sources for REST and WebSocket requests (i.e. http://onehost:8080 <http://onehost:8080>,http://otherhost.com <http://otherhost.com>). If you leave * yo* *</property>* Please share me know the result.
