Error Couldn't verify username because servers are unavaideble

Hey I have a problem on my fresh paper server on my Mac

so some info about my setup
-paper (the newest)
-java 16
-MacBook Pro 16gb
-port forwarding enabled
-firrewal is off
so why I made the server is because I want to play with my friends on Minecraft. I searched and searched for a sullution but nothing helped.
so I wanted to reach out after 3 days trying everything what people did say I tried also every windows solution but they didn’t work either so idk what the problem is

and I know that I can run it in offline but that isn’t handy because I spawn at spawn everytime so that isn’t handy to play survival with

this is the error I have

ERROR]: Couldn’t verify username because servers are unavailable

[10:09:47 INFO]: [email protected] PROFILE NUMEBERS[id=,name=Thijmen_105,properties={},legacy=false] (/MYIPV4) lost connection: Authentication servers are down. Please try again later, sorry!

so this is what I get when I join in console please help me I tried 2 times to make a new server but that didn’t help out either look port forwarding isn’t the problem but also I use my pc to play and the MacBook to run the server on so pls help me

thanks in advance (also tag me because sometimes I can’t see it :D)

sorry for my English I am dutch so my English isn’t the best and 1 thing don’t talk dutch so If it worked other people also can fix it if we found the problem.

update I found this in my console

com.mojang.authlib.exceptions.AuthenticationUnavailableException: Cannot contact authentication server

how to fix that because I think that is the problem

this is the full log of it

Something s wrong with your java installation or network setup in general

ok how to fix that then

ok I am going to update my java and then I will try again is that the problem maybe I am going to check if It is up to date

my java is up to date and all my security is off

then my internet settings what do I need then extra beside port forwarding

I also did flush my dns again

I know the problem check your internet settings because that was my problem :smiley:
