Hello everyone. Thanks for keeping the conversation going. In most cases, a 701 error points to a general connectivity problem. Normally, this will take a bit of troubleshooting regarding the network configuration and how Sonos is integrated.
Submitting a diagnostic report can be helpful for the moderators to take a quick look and advise on next steps.
Alternatively, if you are looking for a more immediate method of troubleshooting, I'd recommend
giving our support technicians a call to troubleshoot this in real time. They can set up a remote session and get a closer look at how data is being routed along the network.
Building community is like building a garden. You build the frame, till the ground, plant the seeds, feed the plants & sometimes you gotta pull the weeds.
