Yes, restrictive firewall settings (either Windows Firewall or router-level), outdated network drivers, a cluttered DNS cache, or a router with UPnP disabled or strict NAT settings can all contribute to connectivity issues leading to Error Code 34203 by hindering the game's communication with servers.
