I’m confused as I don’t recognise those settings. What version are you using?
Edit: Ah, I have just realised the last screen shot is from the NetScan app [APP][Pro] NetScan (Version 2.0.6, Test Version 2.0.8)
maybe a mod could move the above post and this one to the correct place.
In answer to the question, I would recommend increasing the Unreachable checks.
