How to add a satellite to an icinga master with an existing client?

Can you share a screenshot and explain this more in detail. “not ok” can mean anything, and “is wrong” as well - what expected values would you see there?

Without the error from config validation, we cannot really tell you what to do - please provide its output for further analyses.

Also, please use the three backticks wrapped around code blocks, as suggested in this guide: Create topics and master Markdown formatting

Cheers,
Michael
