Well if you have the same problem for all HL1 based games, chances are your computer is being blocked. So you should recheck all firewall and router settings just in case you overlooked something. Also make sure to compare the router allow list firewall to your LAN firewall in case your LAN IP changed without you knowing. That can happen at times if you have your router set so that it gives you an IP instead of a static LAN system.I dont know how to check it out, I knew how to do this on my old one, but I got a new 1 not too long ago
