An existing connection was forcibly closed by the remote host

It seems that some of your PublicEndPoints are not correctly configured to point to a listener IP or port on your server. This cause that error, as there would be no listener available and your server would close by the remote host.

To prevent this, you should ensure that all PublicEndPoints on your server are correctly configured and pointed to your server, or if you use a valid domain name, make sure all DNS are configured correctly. For example, make sure that port 443 at IP address 185...18 is open on your server, and that VpnHood Server is listening to it.

i send error to you intentionally this happened last day and with no change to setup that worked for near 2 week , your suggestion about ip connectivity is done already . we think may be this is the way that censorship can block vpnhood this is from censored country :

and it seems they manipulate https packet when they find IP address (i don't know how and which part of it ) but may be this error can help to mitigate the censorship problem

trudyhood commented 5 months ago

There are many other ways to find a VPN Server's IP. We focused on making it exactly like a regular website, and VpnHood has zero fingerprints.

Make sure you have installed double IP on your server, so the gateway IP should be different than the public IP address,
Using a valid certificate may help.
Make sure you don't publish the server endpoint publicly.

If you have any ideas that you think may help, let us know so we can work on them.
