I’m having trouble getting my Discord bot to run properly. Every time I try to launch it, I keep running into the same issue.
The error message I’m seeing is:
Discord.Net.WebSocketException: ‘Received close code 4012: Requested gateway version is no longer supported or invalid’
I’m wondering if this problem is related to using an outdated version of the Discord.Net library. Maybe I need to upgrade to version 1.0 or higher?
I’m not completely sure if the library version is actually causing this issue though. Is there a way to confirm that the version is the real problem here? And if it turns out that’s the case, would updating the library be my only solution, or are there other ways to fix this?
yep, the 4012 code def means ur discord.net is outdated. they phase out older versions, so just update to the latest one via NuGet and u should be set!
That gateway error indicates that Discord has deprecated the API version your Discord.Net library is using. I experienced this same issue six months ago after neglecting to update my bot for a while. Make sure to check your package references; any version below Discord.Net 2.0 will cause this problem. Discord frequently phases out old gateway versions for security reasons, so it’s essential to stay updated. Updating through NuGet to the latest stable version should resolve the issue. Be prepared to adjust some method calls due to potential breaking changes, but everything else should function correctly.
I hit this exact same gateway error last year on a project bot. The 4012 close code means Discord killed the gateway version your library’s trying to use. Happens when Discord.Net falls behind Discord’s deprecation schedule. Don’t just update the package - check your target framework too. Newer Discord.Net versions need .NET Core 3.1 or higher. After I updated, I had to tweak a few auth methods since the newer versions changed some syntax, but it wasn’t bad. The Discord.Net GitHub repo has a solid migration guide if you run into breaking changes.
