I have just researched installed openssl.

root at LIA-RP-VS-WEB:/etc/nginx/tls# openssl version -a -v -b -o -f -p -d
OpenSSL 1.0.2g  1 Mar 2016
built on: reproducible build, date unspecified
platform: debian-amd64
options:  bn(64,64) rc4(16x,int) des(idx,cisc,16,int) blowfish(idx)
compiler: gcc -I. -I.. -I../include  -fPIC -DOPENSSL_PIC -DOPENSSL_THREADS
-fstack-protector-strong -Wformat -Werror=format-security
-D_FORTIFY_SOURCE=2 -Wl,-Bsymbolic-functions -Wl,-z,relro -Wa,--noexecstack
OPENSSLDIR: "/usr/lib/ssl"

According this note:

Major changes between OpenSSL 1.0.1l and OpenSSL 1.0.2 [22 Jan 2015]:
•ALPN support.

Therefore, ALPN is supported and should work with IE. Am I right?
Actually I should have OpenSSL 1.0.2d 

In addition, the LIA-RP-VS-WEB is a XEN guest. 

Thank you for your tip about chrome. I can see and investigate the protocol
