It's a message FROM the hub
Currently, if you get "You are banned from the hub, if you believe this is an error contact us" it may confuse someone that they have to visit the hub URL where they will be met with a 404 because it's not an actual website. Seems it looks like "contact us to website"
Similarly, with "Failed to contact status address" makes it look like it's an error message coming from robust failing to connect to the hub server. When it's actually coming from the hub, telling you probably don't have your ports open.
I believe changing it to "from" will get the message acros that this is a message from the HUB and not robust.
All HttpClient usages in the engine now use Happy Eyeballs, same implementation as the launcher.
Makes a IHttpClientHolder type so content can profit from this technology too. Didn't make use of this in all HttpClient usages in the engine itself, due to varying circumstances making it annoying to refactor.
