Logout: 502 Bad Gateway

I have the latest version of TML installed.

When I logout I get the “502 Bad Gateway” on the following URL… https://domain.com/logout?_wpnonce=c247a456ee
When I refresh the site (same URL) I get the confirmation where I am asked if I want to logout.

The funny thing is, that I’m logged out the moent I get the 502 error. I tried to set a redirect to bypass the error page, but this isn’t working.

When I deactivate WP Cerber (Security Plugin) the logout is working… But I can’t find the setting which is causing the issue, have deactivated all features one by one.

When I logout I want to be logged out without a confirmation page.

Hope you can help me.
