Dears,
I have LMS 2.6 Installed with DFM 2.0.6, and it was working fine till 3 days ago. the devices in DFM Devices management are shown in Learning State and are not transferred to Known state (this has been the case for three days now).
I tried the following:
1- Rebooting the server with no luck
2- Re generating the SSL Certficiate with no luck too
I am attaching PDShow.txt. please help.
