We need to know what the 503 meaning is. It can be a gateway or another issue.
Use curl -v to try and access https://yum.oracle.com/ and see what the error page shows.

However, the proxy return 503 error when we try to access yum.oracle.com <http://yum.oracle.com/> . Attached the error log and the squid.conf file for your reference. Do I need to do any SSL inspection to make it work ? We already tried to set the company proxy in Cache Proxy setting and also the Windows Server Connection layer. But result the same. The connection is like below. The cache proxy 3.5 is installed on Windows Server Oralce Linux with yum.conf set > Cache Proxy > Company Proxy > Redhat/Oracle Best Regards, Johnny Lam AWS Certified Solutions Architect Security Consultant UDS Data Systems Ltd Office: +852 2851 0271 <tel:+852%202851%200271> , Fax: +852 2851 0155 <tel:+852%202851%200155> Mobile: +852 9504 5848 <tel:+852%209120%207940> China Mobile: +86 14715379352 <tel:+86%209120%207940> URL: http://www.udshk.com <http://www.udshk.com/>
