dnf update throwing the error

[r_upendar]

Dear RHEL SMEs,

I need assistance on the dnf update. the server is running with RHEL 8.2 and behind a corporate proxy server. Is there any way to work around the port 1080 ( SOCKS Proxy port). can we use a 443 or 80 instead of 1080. Kindly advise the resolution steps. Thanks.

My Linux skills are rusty but I believe that technically, it’s possible to work around the SOCKS proxy limitation by using an HTTPS proxy over ports like 443 or 80. That said, it really depends on whether the HTTPS proxy is available in your environment and if IT Security permits this kind of traffic for package updates. Some setups block outbound package manager traffic, even on standard ports, depending on policy.
