Nothing in the other post worked except this..  +server.anticheattoken 0

The certificate I tried, never worked because I couldn't figure out where it was supposed to go and didn't get an answer for it.

Only option so people could log in was to use the +server.anticheattoken 0, but then I couldn't use the F1 console items tab to give myself items. Legit stopped working after the "fix". SO, my question is.... How do I fix the F1 not working anymore?

I don't necessarily know how to fix the "items" tab not working with your "fix", but you could always use the F1 console to "give (item.shortname) <amount>". Not sure if you already tried.

Were you able to fix the issue?

Finally a solution has been found...

You need to have the following set in the server.cfg then it should work ok, at the end is ok. Save and restart server.
server.anticheattoken 0
server.encryption 1

*server.anticheattoken "0"
*server.encryption "1"

I'm trying, but so far it doesn't work

Hello guys.

As i was get this issue "EAC: Verify ID token Canceled" on my server after moved from PC to another one machine.

I was try find the solution i was try all what i was find on the internet, and nothing was help. But after all I Install the server on second machine and BooM all works grate no any issue with "EAC: Verify ID token Canceled" there is also no any issue with firewall or some certificate.

This is how it works as I write it in the server.cfg

server.anticheattoken "0"
server.encryption "1"

This is how it works as I write it in the server.cfg

server.anticheattoken "0"
server.encryption "1"

I was try use you'r solution and did not work. So i just reinstall server as first then i move my map save and data to this server and BooM i did not loose anything from my progress. 

Solution. My server is installed and running on the vds server. When players want to enter the server, they get the error "Disconnected:EAC: Verify ID token Canceled". They couldn't enter the server. Since the server was installed on an old operating system, the "SFSRootCAG2.cer" certificate was missing. I uploaded this file (search and find this file on the internet and install it on the PC where your server is installed) to the vds. Then I restarted the server. The problem was solved.

On Linux, installing the ca-certificates package usually fixes these types of issues. Also perhaps ca-certificates-mono

hmm did just 
cd ~
curl -O https://www.amazontrust.com/repository/SFSRootCAG2.cer
sudo cp ~/SFSRootCAG2.cer /usr/local/share/ca-certificates/SFSRootCAG2.crt
sudo update-ca-certificates

but still had same issue 

i had the same issue, the solution is to make a server.cfg file in wich you put  server.anticheattoken "0"
server.encryption "1" (each on a separate line) and restart your server.
The server.cfg file needs to go in your server\cfg folder, same place where you will find serverauto.cfg bans.cfg and users.cfg
That solved it for me.
