I can’t log in to the hestiaCP panel.
I enter admin, on the next page the password. I am thrown again at entering the user name and so on indefinitely. At the same time, the input form does not say that the password is incorrect.
It should work as intentend as 0 != unlimited if you really need a longer time out increase it to 86400 or even higher I you login once a day on the server you will get logged out.
