I'm working on a server with Ubuntu 18.04 OS.
I've double checked every network configuration.
The "wget" works fine with practically every website I'm trying to download from. Although there's one internal web-site that I'm trying to download from it a certain app and it's no working. I have the same server with the same configuration of network as well as hardware but it runs on Ubuntu 16.04 and there it works fine also on the internal web-site.
Messages I'm getting(a lot of the info on the pic is restricted)
Please advice on how to continue from this point. I'm pretty lost here.
