Unable to connect to Server (UE4)

I'm unable to connect to Playfab servers using Unreal in 4.21.

This problem occured to me once but didn't persist. This time its simply not working for almost a day straight.

The only error message I could retrieve was "Unable to contact server"

I'm using the default "Login with Custom ID".

Any help would be greatly appreciated, as I've tried about anything to fix this the past day.

It seems like a network problem between you and Playfab server, you may test API availability without UE4 to rule out this possibility, and the simple way for it is postman. Waiting for your reply.

But now, we have 2 different servers with 2 different public IP in two different subnetwork, first server successfully establish connection to playfab, second not.

I had the same error stack. A workaround is to have the SSL certs installed on the OS and then set the bVerifyPeer value to false on the Network UE4 settings.
