cobalt not working: why, and what to do now

cobalt is one of the most respected tools in the space, precisely for being open-source and not relying on aggressive ads. But being a community-maintained project with a single official public instance, it also has its own fragile points when demand spikes or a platform changes something. Here are the real causes and what to do in the meantime.

Is cobalt down right now?

It could be. Unlike a service with commercial infrastructure behind it, cobalt.tools' public instance is maintained by a small team, and it can be affected by traffic spikes, by recent changes on some platform it hasn't adapted to yet, or by usage limits the project itself applies to keep the service sustainable for everyone.

Most common causes of cobalt not working

• Rate limit on the public instance: during high-demand hours, cobalt can temporarily limit the number of requests to avoid getting overloaded.
• A platform recently changed something: like any tool that depends on yt-dlp or similar engines, cobalt needs time to adapt to changes from YouTube, TikTok, or other platforms.
• Support paused temporarily for a specific platform: the cobalt team can occasionally disable support for a platform while it works on adapting the code to a change, instead of leaving it throwing errors.
• The specific video is restricted: private, paid, or region-locked; no tool will be able to download it in that case, cobalt included.

What to do right now

1. Wait a few minutes and retry: many of the public instance's usage limits are temporary and clear on their own.
2. Check that the video plays normally on the source platform.
3. If you need the video now and it can't wait, try another tool while cobalt recovers.

Self-hosting your own instance: cobalt's other option

Being open-source, cobalt lets you host your own private instance, which doesn't share usage limits with anyone else. It's a real option, but it requires technical knowledge (your own server, configuration, maintenance) and time dedicated to keeping it updated yourself, so it isn't practical for most users who just want to download a one-off video without complications.

Is it worth waiting for cobalt to recover?

It depends on urgency. If the video can wait, it's reasonable to give the public instance a few minutes or hours to free up or update: cobalt has a good reputation for reacting seriously to platform changes. If you need the file now —for a deadline or a post scheduled for a specific time— it doesn't make sense to depend on a single service without knowing how long it will take; in that case, trying another tool in the meantime is the more practical option.

Why this happens (and not just with cobalt)

These kinds of interruptions aren't a failure exclusive to cobalt: any tool that depends on adapting to constant platform changes goes through the same thing. We explain it in detail in why video downloaders stop working.

PullVid: the same cleanliness, without public usage limits

PullVid shares what's best about cobalt —downloading with no banners or fake buttons— with YouTube, TikTok, Instagram, Facebook, and X from a single tool, without usage limits shared with other users during peak hours. We automatically monitor that the download works on every platform every few hours —check our live status— and we validate every update before publishing it.
