I couldn't restart my app via rhc restart {myapp} after run gem updating. I ran:
rhc restart-app {myapp}
Then they asked me for password.
after typed the password, I see:
Unable to authenticate the user. Please try again and contact support if the issue persists. Reference ID: (A string)
How can I fix it? I also get this error when try to type rhc tail {myapp} and cannot see the log.
