Ignition Edge Device is on Network, but Edge Gateway cannot be accessed

I have moxa edge devices that I am installing , but a lot of them are not able to be logged into. Networking says that all firewall/security/infrastructure is up to date and that the data from the Moxa is flowing how it should. I am not able to log into the Ignition Edge gateway though. The weird part is that I am able to log into a lot of them, but some are just coming up as an error. Using port 8088.
