Hi, everyone, I has installed fusionPBX on AWS lightsail with static public ip address, because I think that static public ip address is easy to control, anywhere I go and there is an internet, I can access to my fusionPBX and make some changes and configurations. the problem is that some places I can not access to my system with internet. sometimes I used 5G on my phone to connect to the system, but it can not connect. what is wrong with it?
