16.1 Legacy Series / lighttpd SSL error records logged every minute in system log.

Dear all,

Every minute the same three lines - displayed below  - are recorded in the system log.

May 17 20:51:22   lighttpd[47368]: (connections.c.1550) SSL: 1 -1 error:140E0197:SSL routines:SSL_shutdown:shutdown while in init
May 17 20:51:22   lighttpd[47368]: (connections.c.291) SSL: 1 error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol
May 17 20:51:22   lighttpd[47368]: (connections.c.291) SSL: 1 error:1408A10B:SSL routines:ssl3_get_client_hello:wrong version number

I don't have a clue why and what can be done to resolve it.
The version I'm running is:

OPNsense 16.1.13-amd64   
FreeBSD 10.2-RELEASE-p14   
OpenSSL 1.0.2h 3 May 2016

What other information could be usefull? I'm running OpenVPN (client) with OpenSSL created by a Debian Wheezy PKI.
Opnsense administration (web)site is protected with a public certificate signed by StartCom Class 1 Primary Intermediate Server CA.

All services are functioning perfectly. Still I'm wondering what the log messages are telling me and how to solve them.

Thanks for any help.

Regards,
Jonkers A.
