Hi Mohamed

You have to check several things to know the root cause of this, as it could be a Firewall between you and the ISE or routing issue or the ISE failed itself or Admin Access restriction).:

  • Telnet from you machine to ISE IP on port 443 and if succeeded then check your browser settings if using IE then go to -- Internet options -- Advanced -- Security -- check if TLS 1.0 is enabled or not (anyway enable all of TLS 1.0, 1.1 and 1.2) if still fails then try Firefox.
  • Try to ping the ISE IP from your workstation.
  • Try to SSH into the ISE and succeeded run this command "Show application status ise" and hit Enter --> and watch the status of Application server service which should be in running state if it stuck in initializing state then you either have to stop and start the ISE services by running the following commands "application stop ise" and wait for a minute and then "application start ise" and wait till the Application server is in running state or reboot the ISE node.
  • Try Console into the ISE (Appliance or VM ) and do the above steps in SSH.
  • If other user has access to the ISE GUI then ask him to check the Admin Access menu to check which IP or Subnet is allowed

Which version of ISE do you use? If it's an older version, try an older version of portable firefox. It could be that your browser is to new. And if that's the case, update the ISE to a recent version.
