In the logging page of the system center, i see in the section dataminer/dataminercore and for all elements only a blank page with the error message:
"Failed getting logfile (the connection with the server was terminated abnormally)"
a reboot of the Dataminer server doesn't help.
The IIS Server shows valid request of the clients to /Tools/Viewlog.asp over https allowed.
has anyone a good idea?
Is the <HTTPS> tag in the maintenancesettings.xml file of your DMA set up correctly? If not configured correctly, it will not be possible to access the logging from the DataMiner Cube UI. You can find more information on the configuration in https://docs.dataminer.services/user-guide/Advanced_Functionality/DataMiner_Agents/Configuring_a_DMA/Setting_up_HTTPS_on_a_DMA.html
