I have the Blackbox AI extension installed in my Visual Studio Code editor. Whenever I try to use it for any coding task or query, I keep getting an error that says “API streaming failed”. The extension doesn’t respond at all.
I’ve already tried several troubleshooting methods to fix this problem:
Cleared all cache files from the AppData\Roaming\Code\Cache directory
Removed cache data from the .vscode folder
Completely uninstalled VS Code, then reinstalled it fresh and added the extension again
None of these solutions worked for me. Does anyone know what might be causing this API streaming error and how to get the Blackbox AI extension working properly again?
Sounds like a network issue with Blackbox servers. I had the same problem last month - switching networks helped me figure out what was wrong. Try using your phone’s hotspot to see if the error goes away. Also check if you’re on a corporate proxy or VPN that’s blocking the API calls. My problem turned out to be DNS issues with my internet provider. Switch your DNS to 8.8.8.8 or 1.1.1.1 and see if that helps. Oh, and check Blackbox’s status page - they might just be down.
Had this exact problem a few weeks ago - super frustrating. The fix that worked for me was checking if I was actually logged into my Blackbox account. The extension needs you signed in, but sometimes your token expires without warning. Go to extension settings, sign out completely, then log back in. You’ll need a Blackbox account first if you don’t have one. Also check if your extension is up to date - mine was old and didn’t play nice with newer VS Code versions. Re-authenticating and updating fixed the streaming error for me.
First, check if Blackbox AI supports your region - they block certain countries automatically. If that’s not the issue, try disabling browser extensions that might be interfering, especially if you’ve got Chrome or Edge running in the background.
This error pops up when the extension can’t connect to Blackbox servers. I’ve hit this across multiple work projects.
First, check your VS Code proxy settings. Go to File > Preferences > Settings and search “proxy”. If you’re behind a corporate firewall or using a proxy, make sure it’s configured right.
Windows Defender or other security software might be blocking outbound connections. I’ve seen this when the extension tries HTTPS requests but gets silently blocked.
Try running VS Code as administrator once - might be a permissions issue. Extensions sometimes need elevated access for network connections.
Check your system’s hosts file too. Ad blockers or security tools sometimes modify it and accidentally block legitimate API endpoints. It’s usually at C:\Windows\System32\drivers\etc\hosts.
If that doesn’t work, open VS Code’s developer console (Help > Toggle Developer Tools) and look for error messages when you trigger the extension. The console shows exactly what’s failing during the API call.
yea, I had a simmilar issue! turned out my firewall was the problem. try turning it off for a bit or add VSCode as an exception. also, make sure your antivirus ain’t blocking those API calls, that was my fix.
