Error Code 316751 in Diablo 4 appears to affect players from time to time, not allowing them to join other people’s parties after getting an invite and/or not allowing them to invite anyone to their party. Luckily enough, there is a way to fix Diablo 4 Error Code 316751.
How to Solve Diablo 4 Error Code 316751
There are a few basic troubleshooting methods that you can attempt to shake things up a bit on the server end of Diablo 4 if you and your friend cannot play together in a party due to the frustrating error code 316751.
1. Restart your games. Yes, this means both of you.
This is probably the simplest troubleshooting method that you can attempt to get rid of Diablo 4 Error Code 316751. If you have just a tad more time, consider logging out, restarting the Blizzard Launcher (Battle.NET), and then logging back in, just in case. Some players also mention that a restart of their PC has helped.
2. Try inviting other people.
This may sound as harsh as “we should see other people,” but it’s only temporary, don’t worry! Try inviting someone else to your party, and if it’s a success, have that person invite your friend and check if this will fix things. If not, there’s one more thing that you can do to do away with Error Code 316751 in Diablo 4.
3. Change Your World Tier
Diablo 4, as you may know, has different difficulty settings, and if you and your friend are on different difficulties (World Tiers), this may cause a “mismatch” of some sort, which disallows you two from being in the same party. So, what you should do is make sure that you are both on the same difficulty and then try inviting each other again.
If you’re brave enough, check how much time you’ve spent playing Diablo 4.
