Hello Mesos experts, I'm trying to setup a master with two slaves on Fedora 29, using the RPM installation. I do have the following problems:
1. I cannot connect to my master on http://mymaster:5050. I get a connection error 2. Checking the logs I do see the following error message repeating periodically: /var/log/mesos/mesos-master.WARNING W0606 23:11:35.007477 63540 authenticator.cpp:513] No credentials provided, authentication requests will be refused W0606 23:11:45.004431 63539 group.cpp:495] Timed out waiting to connect to ZooKeeper.

I went through the documentation and I'm not sure what I'm missing. My '/etc/mesos/zk' has the right URI (not localhost): zk://mymaster:2181/mesos Any suggestions?
