I recently purchased a few music albums and films from iTunes which were subsequently downloaded to my iMac. However I also received this error message " There was a problem downloading “Bridge Over Troubled Water / Seventies Anthems / Simon & Garfunkel”. An unknown error occurred (-54). " for each item I purchased.

I subsequently discovered that all the purchases were successfully downloaded to my other Apple devices, namely my iPhone, iPad and another iMac. The iMac that I am having the problem with was recently wiped clean and a fresh install of Mojave done. My music library and relevant iTune files are on an external hard drive.

Trusting someone can help me with this problem.
