Everything set up perfect, still Global error: Could not authenticate server license key

Hello guys!
I got a really BIG PROBLEM with my server and actually i can’t get over the “Global error: Could not authenticate server license key.” I’ve done 4-5 times all the steps and the result is always the same. Here are some screenshots. If any of you have a big brain, i’m begging for it to solve my problem lmao.

Also, i saw a guy that talked about the keymaster’s servers to be down time to time. Could be that the problem ?

Thanks for your time.

Solved ! If you are getting this error and you have done everything properly, activate the key and let it active for a few hours and then try to start again the server. It will work, just wait and let your key active for a period of time !

Good luck !
