We were able to reproduce this. A workaround is to restart nxserver (/etc/NX/nxserver –restart) after every system restart. Additionally please execute the command ‘chcon -t var_log_t /usr/NX/var/log/nxerror.log’ which changes the SELinux context for that file.
More details about the workaround can be found in the Trouble Report here: https://www.nomachine.com/TR01L04196.
