When you turn on a composite (both Autocomposite and just Composite) site in Bitrix, an authorization error occurs, "Your session has expired, refresh the page" . And if you refresh the page, then the error is not eliminated. Login through the admin panel works, only authorization from the muzzle does not work. If you restart the PHP service, then the first one who enters the site can log in without problems, but everyone who came after him can no longer. The component responsible for authorization votes against the composite.
What I tried:
Twisted PHP settings
Transferred session storage to the database, to memcash
Disabled / enabled session encryption, cookie
Question. Where to dig?
