Hi Team
Can you please let us know what this error means - TAG_NONE/503 in the access logs.
Some times, I get the above error for all the URLs and no one is able to reach the internet and now I am facing the issue only for specific URLs.
The concern is that the issue gets automatically solved without making any changes to any configuration and it comes back again and again and it gets resolved.
The below is the configuration in the proxy server.
###IP Ranges
acl localnet src "/etc/squid/linux_server.txt"
acl localnet src "/etc/squid/server_allowed.txt"
### URL - Allow / Deny
acl allowedurl dstdomain "/etc/squid/allowed_url.txt"
acl denylist dstdomain "/etc/squid/denylist.txt"
acl Safe_ports port 80 # http
acl Safe_ports port 443 # https
acl CONNECT method CONNECT
http_access deny denylist
http_access deny !Safe_ports
http_access allow allowedurl
http_access allow localhost manager
http_access deny manager
http_access allow localnet
http_access allow localhost
http_access deny all
http_port 8080
cache_dir ufs /var/spool/squid 10000 16 256
coredump_dir /var/spool/squid
refresh_pattern -i windowsupdate.com/.*\.(cab|exe|ms[i|u|f]|[ap]sf|wm[v|a]|dat|zip) 4320 80% 43200 reload-into-ims

refresh_pattern -i windows.com/.*\.(cab|exe|ms[i|u|f]|[ap]sf|wm[v|a]|dat|zip) 4320 80% 43200 reload-into-ims
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
refresh_pattern . 0 20% 4320
Could you please let me know what causes these issues and how to give a permanent fix.
Regards
Arjun K.
