In addition, Roon has stopped identifying any new albums I add. Clearly Pink Floyd’s “The Wall” is in the database, but Roon doesn’t identify it or any other albums I’ve added recently. Would this further suggest that Roon is having trouble connecting to your servers?
In terms of simplifying my network, the only thing that occurs to me is to connect the ST directly to the AT&T modem, bypassing the Cisco switch. However, it was previously suggested that in order to resolve dropouts I should connect everything to a good switch to eliminate a possible bottleneck in the modem.
Also, when I try to check my account info in Roon, I get an error.
Looking forward to hearing from @Eric.
PS: Thanks for the suggestion, SJB. I gave it a try, but no help.
