I have a very strange problem resulting with a ERR_TIMED_OUT from one computer, but not from any other computers on the same LAN.
My setup is: XCP-ng with pfsense, HAProxy reverse proxy and a few VM’s running linux servers, such as samba4 active directory, owncloud, homebridge, cloudberry, etc. My domain is .lan and I use HAProxy to reverse proxy to .com on the LAN. It works like a charm, really, wonderful. My Windows 10 clients can connect to all the web servers on the LAN using .com without issues, but one freaking Windows 10 machine that keeps erroring out with ERR_TIMED_OUT. I tried all I could find on the web, including flushing the DNS, resetting the network card, clearing the browser cache, using different browsers, nothing helps.
If you have an idea, please share.
