I have a 2 router situation. I have opened port 5005 on both routers. The router connected to the PC and the VM is open for internal and external port 5005 for the servers local IP and the router connected to that router has the port 5005 open too the router connected to the PC and VM. when i use local ip address the client can connect to the server with no issue but when i use the external ip i get no connection could be made because the target machine actively refused it. I have disabled firewall to see if that was the issue. Any help would be very helpful.

Thank you.
Frustrated noob

Was using the incorrect internal IP address for the router that the bot was attached too. If anyone was wondering. The IP that you use to log into your router is not the same as the assigned ip that the second router gave my router. so if this is your issue that could be your solution too.
