Error message 503
I just updated iTunes and a message keeps popping up saying:
"The shared library âStore Purchasesâ is not responding. (503)
Check that any firewall software running on either the shared computer or this computer has been set to allow communication on port 443."
Everything seems to be working fine but the message periodically keeps popping up.
iMac (21.5-inch, Late 2013), OS X Mavericks (10.9.5)
