@Gargantua This is related to outdated Java SSL certificates still present on your computer.
Your TripleA still uses an outdated Java version that had been bundled with a very old installer despite you updated to the latest Java. Now you need to manually remove that old version.
To find the culprit, please do this:
-Start a Local Game (any will do)
-When the game has started find the Menu Debug and then click Show Console
-When the Console has opened, click the button Properties
-Then click Copy to Clipboard
-Paste in this thread
