Squid tls issues after upgrade

[F00d3r]

Hello,

after upgrading to the 24 release and Squid 6.6 the tls filtering stopped working for me. As soon as I enable the tls filtering, every connection gets bumped, nonetheless the config and in the cache log the following error message shows up or every connection:

kid1| ERROR: failure while accepting a TLS connection on conn3061 local=x.x.x.x:443 remote=x.x.x.x:34312 FD 38 flags=33: SQUID_TLS_ERR_ACCEPT+TLS_LIB_ERR=A000416+TLS_IO_ERR=1

As soon as I uncheck the 'Enable SSL inspection' option within the forward proxy tab, squid starts working correctly.

Any ideas?

Bests,
F00d3r

Did you find a solution to this?
I've just setup a fresh install and getting the same error.

I am also getting this error with pfSense plus

I can still see the ClamAV splash screen as well as my URL blocks however it functions..


Per Squid Developers...

cache_object://URL Scheme is not removed in Squid-6
cache_object://hostname/request@password

Is used to check status inside the pfSense GUI for this package

It has been replaced with
http://hostname/squid-internal-mgr URL-prefix.

Therefore it will now say access denied when checking status

The status page needs to be updated to reflect the new URL scheme

I spoke with Squid user support and they have confirmed the new URL scheme

Ref:
https://wiki.squid-cache.org/Features/CacheManager/CacheObjectScheme

Did OpenSense already fix the status pages?
