Error message: The shared library “Cloud Music Library” 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.

I having problems accessing peripherals and also got this error message trying to access the iTunes store:

The shared library “Cloud Music Library” 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.

I am using a Netgear router but no other firewall.

I also get errors trying to write to my external hard drives. Any one know what this is?

😕

Mac Pro, OS X El Capitan (10.11)
