CentOS

Hello !
I have a problem, when I try to get updates, I get errors:
# dnf update

I can't understand what the problem is, the proxy is registered in the config, Help please

Your proxy id rejecting your attempts to get outside. Perhaps you need to provide it login details.

Hello! could you solve it?
I have the same problem..

The 403 is coming from an ip address 172.16.1.107 which is an RFC1918 private ip address and is thus inside your own organisation. It is presumably some sort of web proxy and you will probably need to authenticate with it to be able to get access outside. Talk to your network admins if you do not understand why this is happening. It is an internal issue that only your organisation can solve.
