Yesterday everything was still fine, but today, most players cannot enter the server using the ip mc.lusiadascraft.pt, they can only enter with the numeric IP. Some friends tried to help, using their domain in their DNS, just temporarily, but I don’t know how I can resolve it to make mine work.
If you create an SHA1 hash for *.lusiadascraft.pt, it yields 1070a474b86c6582e36be805959a803e079cbf75.
If you check that value on https://sessionserver.mojang.com/blockedservers, you will notice that it is on there. That means your domain is blocked by Mojang.
