SSL Errors

Hi all

Trying to get an https test working to monitor certificate expiry.
Test shows up red, with very descriptive "SSL Error".

The xymonnet error appears a little more useful, but I can't find a
resolution to the problem.
Unspecified SSL error in SSL_connect to 47873/tcp on host  1.2.3.4:
error:1411809D:SSL routines:SSL_CHECK_SERVERHELLO_TLSEXT:tls invalid
ecpointformat list

Additional info.

xymonnet version 4.3.17

SSL library : OpenSSL 1.0.1j 15 Oct 2014

LDAP library: OpenLDAP 20423

Any advice appreciated.

Regards
Vernon
