I think this is a dead game. Shut down 14 February 2020 and this was the second time it shutdown too apparently.
AI Overview
"Guardians of Ember shut down due to the expiration of the publishing contract between Runewaker, the developer, and Gameforge, the publisher, without plans for renewal. The contract's end led to the closure of all official Gameforge servers and the deactivation of the payment service, preventing further purchase of in-game currency. There were no plans for character transfers or alternative official servers."
