Cockpit login fails

Thursday, 30 September 2021

Hi,

I tried to use the cockpit on fc34, but the login fails:

Sep 30 12:25:11 bfr.foo.bar.tld cockpit-session[170263]:

Unfortunately I did not find anything regarding the

json_object_get_string_member: assertion 'node != NULL' failed

issue.  /etc/pam.d/cockpit exists and there is also no customized pam 
configuration.

Any ideas?

Best Regards
