I had this error too, with these conditions
DB_CONNECTION = sqlite
SESSION_DRIVER = database
using VPS for hosting (both Apache2 and nginx)
However, everything worked locally, and on two shared hosting platforms
When the site moved to a VPS, all requests other than GET yielded the 419
I tried lots of things but now it's working with
This may not be a a good long term solution, but I plan to switch to a MySQL database.
