Updating 7.2 to 7.3 error 30

So I *might* have found my problem.
https://support.eero.com/hc/en-us/articles/215721143-I-have-a-TP-Link-TC-7610-modem-and-I-m-experiencing-issues-with-my-eero-network
Apparently my Eero doesn't work well with the TP-Link TC-7610 Cable Modem (the cable modem is brand new as the old one died after 7+ years of service).

SO off to try a new cable modem and see if that works.
kiki le schnoodle - do you by any chance have the same setup as me?

In the next day or two I'll post back here to let you know how it goes. Thank you all for the help!

How's it going with the update after those changes wizawuza?

Just ordered the cable modem a few minutes ago =)
Will let you all know very soon!
Fingers crossed

Wizawuza, I am pleased you feel you are making some progress. I do not think the issue for me is my modem and suspect for you possibly also. I have two Sonos play 5 on my system and one bridge. One play 5 will not update to 7.3 from Sonos very 7.2 whilst the other play 5 and the bridge have updated fine to verify 7.3 and are working ok. So you see, if the issue was withy modem, I don't see how only one Sonos device will not update whilst the others do.
I'm using TP-link Archie VR900

It could have to do with the location on the network that that PLAY:5 is taking, but it's hard to say for sure. Do you mind trying again and sending a diagnostic when you get that error? I'll take a look for you. Just post the diagnostic number here.

Diagnostic reference number is 7575872

Thanks. I pulled up the conversation you had with us online as well. I may have missed it going through all the notes, but have you tried rebooting your modem and router, then your Sonos player?

The error message coming up in the diagnostic is a failure to connect to the update servers, actually, it's a failure to resolve the IP of those servers. Specifically, from that player.

The things to test would be a different controller, and checking in the router that the player isn't getting blocked somehow by the firewall or device restrictions. Can you check for access control on the router? If it is a Google Wifi TPlink then it may be set to paused under the family plan in the settings.

Rebooting the router, as I suggested, is a good way to make sure any odd cache isn't getting in the way, and possibly trigger a fresh DNS as well.

If you're still running into trouble at that point, I'd advise giving us a call on our support line. The team will take a look at the system and dig into why that player can't update.

Thanks for the advice. Of course rebooting has been tried previously and no improvement. I doubt MAC address blocking is the issue as that play 5 always used to stream, but I will check the router settings.

I was finally able to update to Sonos version 7.3 after releasing the fixed IP address, reassigning a new one and restarting the router modem. I fail to see an error with the original config but reassigning the Sonos IP address seemed to do the trick

Glad to see your error has been fixed. Thankfully mine has been too once I changed to a new cable modem. Yay!
