Hi @stevenp and welcome to the forum.
Can you please provide a bit more info on your problem so people can actually help you?
Maybe a screenshot, some details on the services or the output of cmk --debug -vv -I yourserver123 command.
Can I also ask you why are you still using the 1.6.0.p30 version? Newer versions maybe already fixed your problem and the 1.6 is technically end of life since 2022-09-09.
Regards
Norm
