Issues downloading UE5

Hello,

I’m having an issue downloading UE5. We switched Internet providers at work,and they have all the ports and domains locked down. I managed to get them to allow access to the launcher, but it is not able to connect to the Internet, so I can’t download new versions of unreal engine. I sent them the list of ports and domains Epic recommends be whitelisted; however, EITS denied the request because the list would open access to fortnight. Is there a way to download ue5 directly? Is there a list of domains and ports that only open the launcher up to download ue5?

Thank you for any help.
