When attempting a DEP sync in the FileWave admin → Preferences, an error: Forbidden is encountered and DEP data does not sync. This error can also show when creating DEP associations in DEP Association Management. 


FileWave Admin
FileWave Server
Apple DEP


There are a few potential causes of this error:

  1. There may have been a change to your server certificate. Check your Preferences → Mobile tab to ensure that your server SSL certificate is not revoked or expired.
  2. There may be a change to the external IP address of your FileWave server. 

Because the Apple DEP service performs a check to ensure that the mdm server is the same (in terms of IP address and SSL certificate) since it was last contacted, you may need to replace the DEP data at with a new public key from the FileWave server. 

You can check the "Last IP Connected" for your DEP account that is giving the error at or depending on what you are using. You will select your MDM Server on Apple's site and you can see the IP listed. Below is a screen shot of where you can view that information.
