Hello All, Thanks for your help, we have resolved the issue once replaced the Old IP with the New IP under "cache_peer" in squid.conf file.

Either DNS has no results, client original dst-IP is not available, or the servers Squid does find are a) forbidden for use or b) currently DOWN according to the dynamic availability checks (ICMP echo, ICP query for cache_peer, and past TCP connection attempts). The cache.log lines immediately following the one you quoted tell the results from DNS and each of those access controls so you can see what the reason for the failure was.
