problem with minecraft premium

Hi some time ago I bought minecraft premium on the site minecraft.net and since then buying minecraft I can not enter any premium server and as if I did not have this premki. If I want to enter a premium server writes me something like Login failed authentication servers are currently in maintenance and that I went to mojang to play originally and I made an account in microsoft at the time of migration and with the version of each what I have 1.8.9 and 1.12 writes me that it does not include security and I can not enter the servers and as I go to the version the only available 1.17.1 it writes that I went to mojanga and I do not know what to do waiting for the answer greet
