Squid/Squidguard blacklist nginx bug ?
yesterday i have upgraded from 2.2.4 to 2.3.1_5.
I use squid/squidguard in transparent mode.
If someone calls a blacklisted http-Site the following nginx-message appears ( instead of the squid-error-message ):
"400 Bad request The plain HTTP request was sent to HTTPS port nginx".
Is that a bug in 2.3.1 ?
Workaround ist to revert to http-protocol in System-Advanced-Admin Access-WebConfigurator.
Maybe this bug will be fixed.
