One of our user feedbacked to us recently some issue after upgrading his Twonky server to the latest 7.3 version. The Pix-Star could not recognize it anymore while it has been working very well before.
We don’t know for sure what happened but in case your frame can’t recognize your Twonky DLNA server after an upgrade, especially to the latest 7.3 version try this:
First uninstall completely any version of Twonky you may have, then reinstall a fresh new 7.3 version.
This solved the issue for him!
