Plex Media Player for Windows 188.8.131.526-608417d4 (on my Lenovo Y520 Notebook with good wireless connection and no extra Firewall or Antivirus just the Windows 10 default)
Plex Media Server for Windows 184.108.40.20685 (on a second PC on the local network)
As the title says I always get ping timeouts when starting Plex Media Player for Windows.
Everything works fine over my wireless connection till the PlexMediaPlayer.exe and/or the PMPHelper.exe is running.
See the video of the problem I recorded:
Quickly see the problem and solution by closing the PMPHelper.exe at 4Min 12Sec in the video.
Update 1: I shut down the Plex Server and only started the Plex Media Player for Windows and the problem is still there, so it has nothing to do with the server.
Update 2: I updated (autoupdate) to Plex Media Player for Windows Version 3.44.1 and the problem is still there.
