Common Issue - Too Many logins - Permission denied

Quite often you might be getting Permission denied due to. too many logins.

Root Cause

We have set a limit for concurrent connections using any user. This is how situation arises

  • Start learning with one session
  • You take break in the middle and come back
  • Idle session get hung
  • You open new session (cannot close others)
  • Once it reaches 5, it will not let you login using new session


  • Do not open more than 3 simultaneous sessions to learn
  • Make sure you close the session by typing exit or ctrl+d if you are taking a break for more than 10 minutes
  • If the issue arises wait for 30 minutes at max and you will be able to login again (we are killing sessions which are idle for more than 30 minutes)
