How to increase the life time of a temporary link to a user profile?

pritunl set app.key_link_timeout does not give a result.

Now like that, but the link is still deleted after 24 hours.

# sudo pritunl get app.key_link_timeout
app.key_link_timeout = 172800

This option is a database expiration index. At least one host will need to be restarted to run the initial database configuration and update the expiration time on the collection.

After restarting the server, the life time of the link is still 24 hours.

root@ip-172-31-32-51:~# sudo pritunl get app.key_link_timeout
app.key_link_timeout = 172800

The label doesn’t change, it will always say 24 hours.
