Good day
I have install ubuntu 22.04 server on 4 machines
The machines are
spark
compute-0-[0,1,2]
spark has an internet connect plus a connection to a restricted
(10.1.1.0/24) network
compute-0-[0,1,2] are on the restricted network
2 of the three compute-0-[0,1,2] machines install with snap ok
but the third fails
I cannot see why
Spot the difference:

acl localnet src 10.1.1.252/32
If someone could indicate why this is happening I would be sincerely
appreciative
The traffic which is failing all seems to have *.internal domain names.
The HIER_NONE indicates Squid either cannot resolve those domains in DNS
or cannot connect to any IP that was found.
Modern Squid are capable of resolving mDNS .local domains. I suggest you
try using that instead of a custom .internal TLD. If you do need to have
that custom TLD, make sure to test those domains resolve through the DNS
server used by Squid.
