Hello everyone,
i'm trying to use squid as a TLS virtual hosting proxy on a system with
a public IP in front of several internal systems running TLS web servers.
I would like to proxy the incoming connections to the appropriate
backend servers based on the hostname using SNI.
I'm using the following config to just try this with 1 backend to test
with and fail already
Here the config:
http_port 3128
debug_options ALL,2
pinger_enable off
shutdown_lifetime 1 second
https_port 0.0.0.0:443 tproxy ssl-bump tls-cert=/root/dummy.pem
acl tlspls ssl::server_name_regex -i test\.regify\.com
cache_peer test.de.regify.com parent 443 0 proxy-only originserver
no-digest no-netdb-exchange name=test
ssl_bump peek all
ssl_bump splice all
http_access allow all
cache_peer_access test allow all
Starting squid gives me the following:

I've been reading the squid docs and other internet resources, but am
failing to figure out why this is not working.
Any clue sticks would be appreciated.
Also appreciated would be advise on where to find this documented.
