Diablo 4 is a highly-anticipated game that has been the talk of the town for a while now. However, like with any online game, there are bound to be some issues that crop up during gameplay. One such issue that Diablo 4 players may face is the inability to join online co-op games, with an error code 316748 being displayed. In this blog post, we will explore some ways to address this problem and get gamers back to playing with friends.

Check the Server Status


One of the first things to do when encountering online connectivity issues is to check the server status. If the server is down, it may be the cause of the problem. It's worth noting that server maintenance and upgrades can cause temporary server downtime, so checking the status is always a good starting point.
  • How to Check the Server Status: Checking the server status is easy. You can visit the official Blizzard website and navigate to the Diablo 4 page. Once there, you will see a section that displays the current server status. If the servers are down, the status will reflect this.
  • What to Do if the Server is Down: If the server is down, there isn't much that can be done except to wait. It's worth noting that server downtime is usually temporary and that Blizzard is working on resolving the issue as quickly as possible. It's advisable to check the server status periodically until it's back up and running.

Check the Internet Connection


Sometimes, internet connectivity issues can cause problems with online gameplay. It's worth checking the internet connection to ensure that it's not the cause of the problem.
  • How to Check the Internet Connection: You can check your internet connection by visiting a website or performing a speed test. If the internet connection is slow or inconsistent, this could be the cause of the issue.
  • What to Do if the Internet Connection is Weak: If the internet connection is weak, restarting the router can help. It's also worth ensuring that there are no other devices consuming bandwidth while playing Diablo 4 online.

Update Diablo IV


Updating Diablo IV can also help resolve the issue. Updates often contain bug fixes and other improvements that could address the problem.
  • How to Update Diablo IV: To update Diablo IV, you can navigate to the game's settings menu and select the update option. The game will then download and install any available updates.
  • Importance of Updating Diablo IV: Updating Diablo IV is essential to keep the game running smoothly. It's worth noting that updates often contain security patches and other important fixes that could prevent future issues.

Repair Diablo IV Files



If the issue persists, repairing Diablo IV files could help. This process will scan for any corrupted files and repair them.

  • How to Repair Diablo IV Files: To repair Diablo IV files, launch the Blizzard app and select the game from the list of installed games. Click on options and select "Scan and Repair" from the dropdown menu.
  • Importance of Repairing Diablo IV Files: Repairing Diablo IV files can help prevent future issues and ensure that the game runs smoothly.

Ask Your Friend to Invite You Instead


If you're still unable to join online co-op games, try asking a friend to invite you to their game instead.

  • How to Ask a Friend to Invite You: To ask a friend to invite you, send them a message or voice chat requesting an invite to their game.
  • What to Do if Your Friend Can't Invite You: If your friend is unable to invite you, you may need to try some of the other solutions mentioned in this post.

Create a Clan to Send Friend Request


Creating a clan and sending a friend request through it is another option to consider.

  • How to Create a Clan: To create a clan, navigate to the clan section in the game menu and select the "Create Clan" option. Follow the prompts to set up your clan.
  • How to Send a Friend Request through a Clan: Once you've created a clan, you can send friend requests to other players through it. Search for the player you want to add, and select the "Add Friend" option.

Contact Blizzard Support


If all else fails, it may be necessary to contact Blizzard support for assistance.

  • How to Contact Blizzard Support: You can contact Blizzard support by visiting their website and submitting a support ticket. Alternatively, you can use their live chat feature or call their support hotline.
  • What Information to Provide to Blizzard Support: When contacting Blizzard support, it's important to provide as much information as possible about the issue. This includes any error messages you've received, steps you've taken to resolve the problem, and any other relevant details.


Diablo 4's error code 316748 can be frustrating, but there are several solutions to try. Checking the server status, checking the internet connection, updating the game, repairing files, asking a friend to invite you, creating a clan to send.
