Fix the issue Hell Runner 2 can't connect to the server
When players are enthusiastically preparing to start a fierce battle, only to be bumped into a "unable to connect to the server" prompt, it can be a bit of a headache. In response to the problem that Hell Trooper 2 cannot connect to the server, we have provided some solutions, hoping to help you solve this problem smoothly and enjoy the game! 
Fix the issue Hell Runner 2 can't connect to the server
First and foremost, optimizing the network is the first step in solving the problem. Using a professional network optimization tool such as Dolphin can improve network stability and reduce latency, which can improve the success rate of connecting to a server for your game. Ensuring that the network is unblocked is the key to solving the problem.
Second, turning off your antivirus software can be an effective workaround. Sometimes, antivirus software mistakenly identifies a game program as a threat and blocks access to the server. Turn off your antivirus software for a while and try to connect to a server again, but make sure your computer is secure after you turn off your antivirus software.
Also, turning off real-time protection may help resolve the issue. Sometimes, your computer's real-time protection can interfere with the normal operation of the server connected to the game. After turning off real-time protection, try connecting to the server again and see if the issue is resolved. Care should be taken to avoid unnecessary risks to the computer.
Overall, you should be able to solve the problem of Helltroopers 2 not being able to connect to servers by optimizing your network, turning off your antivirus software, and turning off real-time protection. Hopefully, the above solutions will help you and make it possible for you to enjoy this exciting game!
