Event 41029, LS Data MCU -- No connectivity with the Skype for Business Web App (port 8060)

[Ramy AMER]

We have SFB 2015 om-prem running latest CU and we can see this error in all our FE server (12 servers) but no users complain!!! I did see other postings but issue related to other error event "HTTP connectivity Event# 30988"  also the port 8060 

Any idea whats wrong?
