Disable your antivirus and firewall:

Sometimes your antivirus or firewall might cause this error, try turning them off and giving it another try. Antivirus and firewall block different connections that they do not feel are safe for transferring data.

A user by the name of fakeluff on the forum stated that relinking your accounts could cause them to re-authenticate your account and might solve the issue

However do this at your own risk since linking your amazon account or steam with lost ark might be vulnerable. I’ve linked articles from the user and how to do this below.
