Well, you had your thread "Default certificate wrongly delivered" about
that issue and it didn't seem to be a haproxy configuration issue.
Several things where suggested in that thread, for example to log the
SNI header and TLS version and ciphers for further troubleshooting, but
you did not provide feedback.
I suggest you go back to that thread and troubleshoot it as proposed;
lets not get this thread here more off-topic than it already is.
