Q: OS X 10.10.4 - Screen Sharing, sometime works, sometime not

Dear All

 

I can't connect to my servers. They all have OS X 10.10.4 (Server 4.1.3). The client has OS X 10.10.4. Both server and the client has no firewall enabled. If I do "Screen Sharing" I see the message "connecting". Ping to the servers are OK. Necessary ports: TCP and UDP ports used by Apple software products - Apple Support on the servers are open. I've deleted all keychain entries for the server in my keychain. I rebooted the servers also the client. No matter, connect by FQN or IP. In the system.log I see the following entries:

It looks for me an authentication issue (Kerberos). But why? Has anybody an idea? Thanks for your replies.

    Same thing happening here with the same error message. 10.10.5. Brand new Macbook behind an Apple Airport Extreme. Won't connect. When on the same network only Apple Remote Desktop (when enabled on the Macbook) can control the machine. The built in screen sharing app gives an authentication failure every time with this type of error in the logs:

    Screen Sharing: RFBViewer.c:8430:AuthenticateKerberosCore: gss_init_sec_context error gss-code: 51183616 A parameter was malformed Miscellaneous failure (see text) -- mech-code: 0 Success
