SSL23_GET_SERVER_HELLO:unknown protocol when updating zimbra 8.8.5 to 8.8.6

[fs.schmidt]

Hello,

I'm trying to update a zimbra environment from 8.8.5 to 8.8.6 and when I ran install.sh I got this error:

SSL connect attempt failed error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol at /opt/zimbra/common/lib/perl5/LWP/Protocol/http.pm line 47.

Does anyone have any idea?

Kind regards.
Fabio
