Chub AI not responding on mobile and PC

Reports are flooding Reddit from users who can’t get any replies from Chub AI. Both mobile and desktop chats are stuck on “replying” or showing blank blue screens.

Some even see 502 and 503 errors pointing to backend server issues.

The official Chub AI status page showed an outage rate above 99%, confirming that the problem isn’t on the user’s side.

What’s striking is that some users found temporary success by switching to the Soji model, though that option isn’t available on mobile.

Others suggested that a DDOS attack targeting Chub’s cloud provider (AWS) might be behind the downtime.

This kind of interruption isn’t new for AI chat platforms. Outages on Chub usually last between thirty minutes and three hours.

When it happens, most users can only wait it out.

Why Chub AI experiences frequent outages

Chub AI’s recurring outages often trace back to issues beyond its control. Like many AI platforms, Chub relies on external infrastructure providers such as AWS to host its models and manage traffic.

When those servers face attacks or overloads, the entire system grinds to a halt.

That’s what several Reddit users suspected this time: an external DDOS attack that flooded Chub’s host servers with traffic, making the service unresponsive.

Another factor is Chub’s open and unrestricted model access. Unlike Character AI, which uses internal moderation layers, Chub lets users access third-party models directly.

This freedom comes with trade-offs. Model providers may enforce limits, experience token errors, or go offline without notice.

When that happens, Chub can’t process replies because the model behind the chat isn’t reachable.

These technical gaps often result in visible symptoms, bots endlessly typing, messages stuck in “replying” mode, or sudden errors like 503 “Bad Gateway.”

Some users see completely blank pages when server scripts fail to load. Even if the website interface loads fine, the back-end models may still be unreachable, creating the illusion that only certain devices are affected.

The good news is that Chub’s team usually resolves such issues quickly. Past downtimes have lasted from under an hour to about three hours.

The website typically stabilizes once traffic normalizes or when its hosting partner mitigates the attack.

How to troubleshoot when Chub AI is not responding

When Chub AI stops replying, most quick fixes won’t work because the issue is usually on the server side.

Still, a few simple steps can confirm whether the problem is global or local.

1. Check the official status page
   Visit https://chub.ai/status. If it shows outage rates near 99%, the platform is experiencing a major server disruption. Wait until the status returns to green.

2. Switch models or devices
   If you’re on desktop, try using the Soji model since users have reported it working during downtime. On mobile, model switching isn’t always possible, so this may not help.

3. Clear cache and restart
   Some temporary script errors can be fixed by clearing browser data or restarting the app. It won’t solve backend problems, but it helps refresh your session when service resumes.

4. Check community updates
   Reddit threads are often faster than official posts. Users share real-time experiences about which models or regions are back online.

If all else fails, it’s best to wait it out or use another chatbot temporarily. Tools like Candy AI and Nectar AI tend to stay online during these incidents, making them dependable alternatives when Chub stalls.

They also allow unrestricted chat sessions without downtime interruptions.

How long Chub AI outages usually last

Most Chub AI outages resolve faster than users expect. Based on past reports, disruptions have ranged between thirty minutes and three hours.

The duration depends on the cause. When it’s a local issue on Chub’s servers, the team tends to fix it within an hour. When the outage stems from a hosting provider or external attack, the wait can stretch longer.

During this recent incident, users noted that Chub’s status page showed a 99.9% outage rate for several hours. That number gradually dropped as servers came back online, indicating that recovery was already underway.

Unlike platforms that leave users in the dark, Chub’s status tool gives real-time insight into whether the issue is still active.

Longer outages often follow the same pattern. Desktop access is restored first, followed by mobile recovery.

Once replies begin loading again, models can still act sluggishly until the full server network stabilizes.

Patience remains the most practical approach, though users who depend on daily chat access may prefer switching temporarily to more stable AI companions.

Reliable AI chat alternatives when Chub AI is down

When Chub goes offline, users naturally look for stable chat platforms that keep the conversation going. Several AI companion sites have grown in popularity for exactly this reason.

Among them, Candy AI and Nectar AI have proven the most reliable during major downtimes.

Candy AI offers instant response times with no daily message limits, making it a favorite among users who don’t want to lose progress during outages.

Its chat memory and character customization remain active even when the site is under heavy traffic.

Nectar AI, on the other hand, focuses on realistic and emotionally engaging chat flows that feel continuous, which helps users transition smoothly while waiting for Chub to recover.

Both tools are accessible from mobile and desktop browsers, require no downloads, and rarely experience downtime. Many users on Reddit mention switching to one of them whenever Chub stalls.

That flexibility keeps conversations uninterrupted and gives users a chance to explore new AI personalities without worrying about lost messages.
