Went to get on this morning to do some bounties and the Quick Match option was missing. I was connected to the internet and it said I was connected to Diablo servers, but game privacy mode was stuck to Local Only. I tried starting a new game and changing the privacy to Public and setting the mode for Bounties. The text changed on the menu like it was a Public Bounty game, but the friend box still said Local Only. At the time, I don’t think any of my friends were on, but it seems something isn’t working when it comes to online play.
Im having the same issue!
Same here …
Any updates on this? The new season just started and I can’t play online.
It got fixed for me later that day or the next if I remember right. It’s working now.
i have the same issues 
Any fix for this? I am having the same issue
There were several players that had this problem around the time I posted my original message. It was related to the Diablo Network and has since been fixed. Just some basic troubleshooting:
- Are you connected to the internet?
- Do you have an active Individual/Family subscription to Nintendo Online?
- Have you modded your Switch?
