by Viktoria Ivanova 57 views

Hey guys! Running into the frustrating "Sorry, your request failed" error in VS Code? Specifically, the one with the net::ERR_FAILED error code? You're not alone! This issue seems to be popping up for some users, and it can be a real headache. Let's dive into what might be causing this and how you can troubleshoot it.

Understanding the Issue

The error message, "Sorry, your request failed. Please try again. Request id: 32ecb1af-d2c5-49ba-9ecd-3033905dfd92," coupled with "Reason: Please check your firewall rules and network connection then try again. Error Code: net::ERR_FAILED," gives us some clues. The net::ERR_FAILED error generally indicates a problem with the network connection or the ability of VS Code to access the internet. This could stem from a variety of sources, from firewall configurations to network connectivity hiccups.

Key Details from the Report

Before we jump into troubleshooting, let's break down the key info from the user's report:

  • Extension version: 0.30.0
  • VS Code version: Code 1.103.0 (Universal)
  • OS version: Darwin arm64 24.1.0 (macOS)
  • Error Code: net::ERR_FAILED

These details help us narrow down the potential causes and ensure that the troubleshooting steps are relevant to the user's setup. The fact that they're on macOS is a good starting point, as firewall and network settings can sometimes be a bit tricky on Macs.

Troubleshooting Steps: Let's Fix This!

Okay, let's get down to the nitty-gritty. Here's a step-by-step guide to troubleshooting this net::ERR_FAILED error in VS Code:

1. Check Your Network Connection:

  • Basic Connectivity: This might sound obvious, but first, make sure you have a stable internet connection. Try opening a webpage in your browser or running a speed test. If your internet is down or flaky, that's likely the culprit. A strong and stable network connection is crucial for VS Code to function correctly, especially when extensions or online services are involved.
  • Wi-Fi vs. Ethernet: If you're on Wi-Fi, try switching to an Ethernet connection (if possible) to rule out any wireless issues. Sometimes, Wi-Fi signals can be intermittent, leading to these kinds of errors. Ethernet connections, being wired, tend to be more reliable.

2. Firewall Check:

  • Firewall Settings: Firewalls are designed to protect your computer, but sometimes they can be a bit overzealous and block legitimate applications like VS Code. You'll need to check your firewall settings to make sure VS Code isn't being blocked. Firewall configuration is a common cause of network-related issues in applications.
  • macOS Firewall: On macOS, go to System Preferences -> Security & Privacy -> Firewall. Make sure the firewall is turned on, and then click "Firewall Options." Look for Visual Studio Code in the list of allowed applications. If it's not there, add it. Properly configuring your macOS firewall is key to allowing VS Code to access the internet.
  • Third-Party Firewalls: If you're using a third-party firewall (like Little Snitch or a firewall included in your antivirus software), check its settings as well. These firewalls can sometimes have more restrictive rules than the built-in macOS firewall. Third-party firewalls often require specific configurations to allow applications to connect to the internet.

3. Proxy Settings:

  • Proxy Configuration: If you're using a proxy server, either for your entire system or specifically for VS Code, double-check that the proxy settings are configured correctly. Incorrect proxy settings can prevent VS Code from accessing the internet. Incorrect proxy settings are a frequent cause of network connectivity problems.
  • VS Code Proxy Settings: VS Code has its own proxy settings that you can configure. Go to File -> Preferences -> Settings (or Code -> Preferences -> Settings on macOS) and search for "proxy." Ensure that the settings are correct for your network environment. VS Code specific proxy settings can override system-wide settings, so it's important to check them.
  • System Proxy Settings: Also, verify your system-wide proxy settings. On macOS, go to System Preferences -> Network -> Advanced -> Proxies. Make sure the settings here match your network configuration. System-wide proxy settings can affect all applications on your computer.

4. Extension Interference:

  • Disable Extensions: Sometimes, an extension can cause network-related issues. Try disabling extensions one by one to see if that resolves the problem. Extension conflicts can lead to unexpected behavior in VS Code.
  • Identify the Culprit: To do this effectively, disable all extensions and then re-enable them one at a time, restarting VS Code after each one. If the error reappears after enabling a specific extension, you've found your culprit! Systematic extension disabling helps pinpoint the problematic extension.
  • Report the Issue: Once you've identified the problematic extension, consider reporting the issue to the extension developer. They can then investigate and fix the bug. Reporting extension issues helps improve the VS Code ecosystem for everyone.

5. DNS Issues:

  • Flush DNS Cache: Sometimes, outdated DNS information can cause network problems. Try flushing your DNS cache to ensure you're using the latest DNS records. Flushing the DNS cache can resolve issues caused by outdated DNS information.
  • macOS DNS Flush: On macOS, you can flush the DNS cache by opening Terminal and running the command sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder. You'll be prompted for your administrator password. The macOS DNS flush command clears the local DNS cache.
  • Change DNS Servers: If flushing the cache doesn't work, try changing your DNS servers to a public DNS service like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1 and 1.0.0.1). Using public DNS servers can sometimes improve network resolution and speed.

6. VS Code Reinstallation:

  • Last Resort: If none of the above steps work, try reinstalling VS Code. This can help resolve any issues with the VS Code installation itself. Reinstalling VS Code is a drastic measure but can fix underlying installation issues.
  • Clean Reinstall: Before reinstalling, make sure to completely remove VS Code, including its settings and cache files. This ensures a clean installation. A clean reinstall removes all traces of the previous installation.

7. Check for Conflicting Software:

  • Antivirus Software: Some antivirus programs can interfere with VS Code's network access. Try temporarily disabling your antivirus software to see if that resolves the issue. Antivirus software interference is a less common but possible cause of network issues.
  • Other Applications: Similarly, other applications running on your system might be interfering with VS Code. Close any unnecessary applications to see if that makes a difference. Conflicting applications can sometimes cause unexpected network behavior.

Diving Deeper: Analyzing the System Info and A/B Experiments

Let's take a closer look at the system information and A/B experiments provided in the report. This might give us some additional clues about the problem.

System Info Breakdown

  • CPUs: Apple M4 (10 x 2400): The user is on a relatively new Apple M4 chip, which shouldn't inherently cause any issues with VS Code. The Apple M4 chip is a powerful processor and generally compatible with VS Code.
  • GPU Status: The GPU status seems mostly normal, with most features enabled. The "direct_rendering_display_compositor: disabled_off_ok" might be worth investigating further if graphics-related issues arise, but it's unlikely to be the root cause of a net::ERR_FAILED error. GPU status is more likely to affect rendering and display issues than network connectivity.
  • Memory (System): 16.00GB (0.08GB free): The user has plenty of memory, so this is unlikely to be a factor. Sufficient memory is important for VS Code's performance, but not usually related to network errors.

A/B Experiments

The A/B experiments list is quite extensive, and it's difficult to say definitively if any of these are causing the issue without further testing. However, some experiments related to Copilot, Python, and network features might be worth investigating if the problem persists. A/B experiments are used to test new features and can sometimes introduce unexpected bugs.

Specific Experiments to Watch

  • dwcopilot:31170013: This experiment is related to GitHub Copilot, an AI-powered coding assistant. If the user is experiencing issues with Copilot, this experiment might be a factor. GitHub Copilot experiments can sometimes affect network connectivity if they involve online services.
  • pythoneinst12:31285622, pythonrdcb7:31342333: These experiments are related to Python development in VS Code. If the user is working with Python, these might be relevant. Python-related experiments could potentially cause issues if they involve network operations.
  • usemarketplace:31343026: This experiment likely relates to the VS Code Marketplace, where extensions are installed from. If there are problems accessing the Marketplace, this experiment could be involved. Marketplace experiments might affect the ability to install or update extensions.
  • agentclaude:31350858: This experiment may relate to integration with the Claude AI assistant, which could involve network communication. AI assistant integrations might cause network issues if they rely on external services.
