AMC Enterprise Edition authorization error: can't connect to server (AER-3881)


I have a doubts with an enterprise AMC version.

I set security enabled and have created new user with all roles enabled, when I try to log in through aql or php client - my user passes authorization as well. But when I try to connect through AMC - I geting an error - Can’t connect to server. I read manual and tried to set access-address - but server still returning can’t connect to server error message. Please help.


Are you getting a prompt to log into AMC?


I get the login prompt like this (server localhost, port 3000, and not only for admin user)


Hi, Can you please provide us below details:

  • Log file (/var/log/amc/error.log)
  • AMC Version
  • Aerospike Version
  • Is bcrypt installed on the system where amc is running?


AMC Version: 3.6.0

Aerospike version: Aerospike Enterprise Edition build 3.5.9

Perhaps there is something wrong in python on server



We checked again for the above mentioned setup of Aerospike and AMC but everything works smoothly. May be there is something wrong with user-role-privileges mapping or with python on server. Could you please restart AMC once and check if it works ? Also if you could provide us user-role-privileges mapping, then that would be great.




Hey, do you mind stating the version of Python and which aerospike client you have (pip list | grep aero)? Also, a code sample of the script would help in debugging this.



The problem @netstar is having is with AMC, not the Python client. AMC uses


Damn, my fingers were itching for a new JIRA ticket. I’m sure something else will come along :stuck_out_tongue_winking_eye:



We reproduced this issue in one of our instance, we fixed this issue and will add fix in next AMC release.



Thank you! please let me know when this release will be able to download.
