deploy with fly.io get Invalid CSRF token error

[zouyq]

I deploy wallabag into fly.io with dockerfile,sometimes get Invalid CSRF token. when login;

After completing the deployment, sometimes I can log in successfully for the first time. However, after successfully logging in and making some configuration changes, it automatically logs me out. Upon logging out, when I try to log in again by entering the username and password, it redirects back to the login page. Clicking again leads to an error: "Invalid CSRF token." Subsequently, I am unable to log in successfully. It's very strange. this is my fly.io toml file

Hello @zouyq,

wallabag relies on session data for keeping users logged in and temp data like csrf tokens for forms. For that these data are either stored on the filesystem or in a cache system like redis.

You may need to check that the folder var/sessions is persisted on your Fly Machine to survive redeploy or restart.
