Not in this regard.

The only IPv4/IPv6 related limitation in 3.4 is that IPv6 address
cannot be used to contact server IPv4 address and similarly no IPv4
use to contact server IPv6 address.
eg the problem which earlier versions needed to use the special
"ipv6"/"ipv4" ACL matches for is fixed.

More likely the credentials are not available at the time the tests
are being run.

Unknown, unknown, unknown. More info is required to diagnose what the
problem is. In particular:

 what does squid.conf contain?

 what server domain *and* IP(s) are being contacted?
  (all of the IPs)

 what does adding "debug_options 28,4 " produce in cache.log?
  (be aware this may have large amount of output, we only need one or
two requests details)
