After switching from GPO to a software deployment tool to deploy the SEM client to many machines at once, the client installation works, however the logs don't appear in the SEM Management Console. Per SolarWinds documentation, the installer.properties file was used and put in the same folder as the local installer. However, the spop.conf file doesn't appear to get the information from installer.properties, which shows only a single line (no carriage returns) as follows (port numbers not shown here, but they were correct):
I am not sure why it didn't get the server address, which is given in the installer.properties file referenced during installation. However, even after manually correcting spop.conf, no logs from these clients appear in SEM console.
You may need to contact support if you have not already done so. This link is to the troubleshooting guide for a 64 bit SEM agent, but I don't think this will help you much unless you have a port related issue. https://support.solarwinds.com/SuccessCenter/s/article/Troubleshoot-LEM-agent-connections-64-bit
