This link has been outdated for years.
This is the correct address to register with the dice server:
https://dice.marti.triplea-game.org/
Where have you taken the screenshot from?
Welcome to the forum.
As of writing this, the MARTI dice server returns an error message in TripleA.
The issue has already been reported:
https://github.com/triplea-game/triplea/issues/1523
Just tried it - still down. :cry:
Yes, according to the conversation on Github there might have been a server crash last night.
The issue has been resolved - the dice server works again.
Thanks P@nther
