Bonsoir a tous,
Je m-apelle Catalin, et je besoin d'aide. Ca c'ete tout ma Francais, car je puex expliquer mieux en Anglais. :)
Recently, I had to switch from http to https. I have modified the IP tables of Linux server to block http and allow https.
As we are running on geo-redundancy we have 2 similar servers with the same function.
After this change, I'm able to access by https only one server out of 2. 
Taking a dump, I can observe that after Client Hello, I get, Alert: Handshake Failure.
For successfull one TLS V1.2 is used
For unsuccessful one TLS V1.0 is used
(how can I make sure that same TLS V1.2 is used for unsuccessful example)
I'm using the same browser IE for both servers.
Extrachecks:
On firewall, both destinations are part of the same zone.
I have compared ssl.conf file between the two servers and there is no difference.
Merci beaucoup,
Catalin
