Proxies failing to connect.

[KnowingCube]

Describe what you noticed and did

I opened the proxy manager of the given sandbox, entered the proxies details. Launched the sandbox opened steam & web browser, the proxy supplier I am using limits my bandwidth so I know when I am using the proxy and if its working cause I can see the used bandwidth. Once steam was opened I started downloading a game just for a few seconds to just see if the proxy is properly connected which when I check the bandwidth it had not changed, which I feel indicates the proxy isn't connected to steam.exe and I am unsure of how to get it to properly connect. Also I ran the proxy test, it always fails on the second step, I reached out to my proxy provider and they stated they did everything they could to fix it but it would have to be something on sandboxies end as they went and tested all the proxies I purchased, and confirmed they are all working and good.

How often did you encounter it so far?

Whenever I launch the sandbox that has a proxy connected to it. And or run the Proxy tester.

Expected behavior

Well if the proxy was connected to steam I would expect the bandwidth used on the proxies to rise. Which it failed to do.

Uninstalled and reinstalled completely fresh sandboxie and the issue still occurs. As it fails on the second step of the proxy check everytime. They advised me to use proxifier if possible but through reading and attempting to install it under the sandbox I couldn't get it to work. They also stated it looks like sandboxie may be using the same proxy connection / test as proxifier so I am not sure if that is an issue. I am really just unsure where to go from here.

You need to use an IP address instead of the domain.

Ive tried to use just the Ip, it doesnt allow me to connect to the proxy at all. So the alternative option the proxy provider said was the domain, and then use the Port assosiated with the ip i wanna use and it will connect me to that proxy. Every other time ive tried to use the ip, port, pass, user format it never worked.

Ok so I've contacted my proxy providers support once again to see if they support Ip:port format within the proxies they supply, and it turns out they do but its a bit weird and is probably why this fails to works. They require pining the domains server to get an ip which when followed by a port will allow you to connect to a given proxy. This works but its super slow loading and when it gets into the steam game that im trying to play it fails when connecting to a server, stating it can't connect to VAC servers. Now i think this is because the ip im given its rotating and not set and therefore cant form a stable strong connection or because my supplier doesn't support gaming related connections with their proxies. So im reaching out now in hopes to find another provider that does support static IP:port proxies that I can purchase and use. Thankyou. Also Sidenote does this mean Sandboxie doesn't support the endpoint:port method thanks.

The proxy server may seem to function correctly during tests conducted through the interface when a domain name is specified in the address section of the NetworkUseProxy setting. However, this setting only supports IP addresses in the address field, so the proxy server will not be used if a domain name is provided.

Additionally, connecting to VAC-protected servers may not be possible when running games under Sandboxie, regardless of whether a proxy is used.
