Mac App Store: we could not complete your update the server gave an error during download: 403 Forbidden I wish to update Xcode with Mac App Store and receive this error

we could not complete your update the server gave an error during download: 403 Forbidden




I am logged in with my AppleID. Other updates working fine, only Xcode not.

Warning: Your Xcode (7.3) is outdated
Please update to Xcode 7.3.1.
Xcode can be updated from the App Store.
I'm also getting this same issue trying to download it.

edit:

This problem is from using a proxy service. In my case it was Privoxy. Temporarily disabling these proxy services would likely help. The problem may arise because of where Xcode is hosted?

Try disabling your proxies.
