I’m experiencing issues with running my Discord bot
Whenever I attempt to start my Discord bot application, it crashes right away and displays the following error message:
Discord.Net.WebSocketException: 'Received close code 4012: Requested gateway version is no longer supported or invalid'
I’m curious whether this problem is due to an outdated version of the Discord.Net library. Is upgrading to version 1.0 or newer necessary to resolve this issue?
How can I verify if the library version is the actual cause of this problem? Are there any other options available besides updating the package? Any help on troubleshooting this gateway connection error would be greatly appreciated.
yeah, that’s def an outdated library issue. had the same thing happen when discord updated their gateway stuff last year. check your discord.net version in nuget - if it’s below 2.x, you’re gonna have issues. updating fixed it for me, but u might have to tweak some event syntax after.
Everyone’s right about the outdated library, but manually fixing breaking changes gets old when you’re managing multiple bots.
I deal with this constantly at work. Discord updates their gateway versions regularly, and tracking these changes across different projects sucks.
Automating the monitoring process works way better. Set up checks that watch your bot’s health, catch gateway errors, and alert you when stuff breaks.
You can automate version checking across all your Discord projects and get warnings before things die. No more scrambling when your bot randomly stops working.
I’ve been using Latenode for this workflow. It connects to your repos, monitors API changes, and triggers deployments when updates are needed. Beats manually checking and updating each bot.
For now, update Discord.Net to the latest version. But automate this so you don’t get blindsided again.
Gateway version 4012 errors occur due to the use of an outdated Discord.Net package that no longer aligns with Discord’s current API protocols. I faced a similar issue about six months ago with a moderation bot I was developing. Discord had deprecated older gateway versions, prompting library maintainers to push updates. The simplest solution is to upgrade Discord.Net to the latest stable version; this should resolve the issue immediately. It’s advisable to confirm your current version through your project file or package manager console first. Also, remember to back up your project before making the upgrade, as newer versions may introduce breaking changes that require code adjustments. My upgrade experience was relatively smooth, involving only minor syntax changes for event handlers.
This error indicates that your Discord.Net version is incompatible with Discord’s current gateway standards. I encountered a similar issue with an older bot that hadn’t seen updates in several months. Discord frequently deprecates support for outdated gateway versions, which is essential for ensuring security and performance, but it also necessitates that we keep our libraries up to date. Before you proceed with updating, verify your Discord.Net version in your .csproj file or via NuGet Package Manager. While you can try restarting your bot a few times for a temporary fix, it’s not reliable. Ultimately, upgrading is the key solution; I had to make adjustments to my command handling when I transitioned to Discord.Net 3.x, but their migration documentation was quite helpful in addressing the majority of breaking changes.
