Error assigning Fortitoken: FortiCare unreachable
Hi everyone,
Every time I try to assign a new token and save the configuration, the error "FortiCare unreachable" comes out.

What I already checked:
- Old users can use the fortitoken. This error only comes out when I try to assign a new fortitoken to new users.
- I have available tokens to assign.
- I followed this page in the forum: https://community.fortinet.com/t5/FortiGate/Technical-Tip-FortiCare-is-unreachable/ta-p/205109

- I also tried this page https://community.fortinet.com/t5/FortiGate/Troubleshooting-Tip-FortiCare-unreachable/ta-p/205343 and here is the output of the command "show system fortiguard".

Fortinet's model is FortiGate 50E and firmware's version is v5.4.1,build1064 (GA)
Please let me know if you need more information or command outputs.
Thanks in advance.
