Unable to add a new node -> Server status "error"

[mfathi91]

After I add a new server in "Server List" section, the status of the server becomes error

After this, when I want to add a new node in "Node List" section, it gives me this message:

OS: CentOS 7
Browser: Mozilla Firefox

Hello, friend. Please make sure that you can communicate between core and tp first. Open port of core 8100
