Unable to contact server

Hi, I've already push and uploaded the game server. But when the game server runs on the backend, seems the server is unable to contact any server using API. The game server tries to call the GetEntityToken function but seems to get an error called "Unable to contact server". Can you guys help on this? Thank you.

Please delete the secret key in the server logs you provided as it may be used to hack your game. You may need to create and use new secret key.

According to the server logs, it seems that the CA certificate is missing, you may try the solution in MpsSamples/amazon_root_ca.md at main PlayFab/MpsSamples (github.com) to install the certificate manually. Alternatively, you may try unchecking "verify peer" in your UE project settings.
