Hello

If you have any firewalls between the host and the tacacs, test to make sure the tcp port 49 being allowed.

telnet 10.x.x.143 49

Hi,
Have you checked the logs on the Tacacs server? Could be an issue with the key not matching.

Thanks

test from the device , telnet to port 49, fail - but this is not the indication as other device registered also not able to telnet port 49, also there is no FW in between, it is MPLS line

refer to the attachment, it is registered in the ISE, but i will ask the Admin to check the log

I open debug tacacs & debug aaa authenti - but there is no debug apprear

Hello

Tacacs uses port tcp 49 , if you don't get a response from this port then I suggest to look as to why its failing, its the possible root cause to your probem.
