Hi @Sridhar_Ganti,
We’re thrilled everything is back online and you’re able to sit back and enjoy playback across devices.
Feel free to send me a PM, but I’m happy to provide a description here. It sounds like you successfully performed both bootups, which restarted RoonServer twice and allowed the change to take effect. That’s why Qobuz connectivity was restored after your second reboot.
At this time, Roon does not generally support IPv6 outside of limited situations. Since it appears you’re using an IPv6 network, we’ve temporarily disabled Roon’s inbuilt DNS lookup to prevent Roon from receiving IPv6 DNS queries. Please note that this is a temporary fix while we work on a more permanent solution.
Also note that this change is limited to your Roon account and Core device; Roon doesn’t have the ability to change your network settings directly, only how your Nucleus+ is interacting with the network. The fact that your mobile devices initially wouldn’t connect after rebooting the router is likely a symptom of broader network settings affecting IP address assignment.
