Installing the certificate and Hosts manually

If you’re having troubles connecting to Datenshi or the switcher doesn’t install the certificate properly, you can try installing it manually.


  • First, download the certificate by clicking here
  • Then, open cert.cer
  • Click Install certificate…
  • Click Next
  • Select Place all certificates in the following store (second option), then click Browse…
  • A new window will pop up, select Trusted root certification authorities and click Ok
  • Click Next
  • Click Finish

If everything else fails…

…you can try to remove all existing Datenshi certificates and install the certificate again. Follow these steps:

  • Press Win+R
  • Type mmc certmgr.msc in the run box and press enter to open the Certificate Manager
  • Select Trusted root certification authorities on the left
  • Select Certificates on the right
  • You should see some * entries in the list. Select them, right click and click on Delete
  • Select all the positive options (Ok/Yes etc)
  • Restart the switcher, click on Inspect, then choose Install certificate, then Yes
    If the inspect dialog is fine but you still can’t connect to Datenshi from the game client, try running osu! as administrator.
