Please help me fix the error: ssl23_get_server_hello unknown protocol.

The detail problem: Error TM1 Login Server URI Error appears when I click the validate button on the Planning Analytics Workspace Administration Tool:

“EPROTO 139647280936768:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:,./deps/openssl/openssl/ssl/s23_clnt.c:794″

What is the cause of that issue? How to fix it?

I look forward to seeing everyone’s answers. Thanks a lot.

    The cause:

    The error ssl23_get_server_hello unknown protocol appears because the server that is cited for the HTTPPortNumber used in the TM1 Login Server URI has UseSSL=F set.

    Solution:

    To fix the issue, just set UseSSL=T and restart this specific TM1 server.
