Agent Answers are not appearing although they appear in the list of execuctions as successful - Flowise Cloud

[alfaroukhesham]

Hello Flowise Community,

I am trying to reach out for the Flowise support team to raise an issue, like specified on the title, the answers are not appearing within the cloud chat and the embedded chatbot on my website. I believe that this has happened before due to an AWS outage, as I have seen such issues appear in late last year. I would appreciate if this gets the attention of the flowise team.

Thanks in advance

I am experiencing a persistent issue with Flowise Cloud where my agents and chatflows are not responding to queries, even on the simplest setups. Here's a detailed description of the problem:
Symptoms:
When I send a query in the built-in Chat interface (e.g., a simple "Hello"), the agent shows "typing..." indefinitely or simply stops without any output.
The Executions/Predictions section remains completely empty, even after multiple tests via the Chat (not node tests).
This happens on both existing and newly created flows (simple chatflows with just Start → LLM → End).
API tests via curl (e.g., POST to /api/v1/prediction/{flow_id}) sometimes return JSON responses, but the UI chat does not display anything.
I have tried on a brand new account, and the issue persists there as well.
What I've Checked and Tried:
Credits/Billing: Fully paid and sufficient (e.g., >$X remaining).
API Keys/Credentials: Valid and tested (using OpenAI/Groq/Anthropic models like gpt-4o-mini).
Deployment: Saved and Deployed flows multiple times.
Browser/Environment: Tested in incognito mode, different browsers (Chrome, Edge), cleared cache, no VPN/adblock issues.
Simplification: Removed all tools, used basic prompts – still no response.
Workarounds: Recreated flows from scratch, exported/imported – no change.

Hola me remito al mismo problema en su plataforma de Cloud, hemos notificado a soporte, pero no tenemos respuesta aun.
Esto esta pasando desde esta madrugada Feb 16, 2026 3:00 PM aproximadamente.
Tenemos agentes en producción sin operatividad posible. Se agradecería una pronta respuesta.

I think we need to look for an alternative. Flowise! I'm in the same situation as you. Nothing works! And the customer service isn't responding. Have you considered alternatives? What do you think? N8N, dify...?

Tenemos infraestructura de Dev auto-hosteada y funciona correctamente, el problema esta en la infraestructura de producción de Cloud.flowiseai.com , esperaremos unas horas y si no tenemos respuesta buscaremos una alternativa hosteada o bien AWS. Veremos a ver como evoluciona, lo peor es no tener respuesta alguna desde soporte o algún centro de soporte online. :(

It worked, I don't know what the reason was, I sent them a request about the problem Through https://www.skool.com/@leon-van-zyl-3419?g=agentic-labs, and it turned out that it worked almost immediately

[infoshpieg-sys]

Similar situation. Let's wait. If you learn anything, please write here. I'll do the same.

Buenos dias, he comprobado que ya esta funcionando el sistema, aun asi no hemos obtenido respuesta de cual fue el problema de origen ni la resolución mediante el mail enviado a soporte.

Execution succeeds but response not appearing = likely a frontend/streaming issue.

Diagnostic steps:

1. Check browser console

   • F12 → Console → Look for WebSocket errors
   • Network tab → Filter WS → Check connection status

2. Test API directly

   curl -X POST https://flowise.cloud/api/v1/prediction/xxx \
     -H "Content-Type: application/json" \
     -d "{\"question\": \"test\"}"

   If this returns response, issue is UI/streaming.

3. Disable streaming
   In chatflow settings, try:

   Streaming: OFF
   

4. Check embedded widget config

   <script>
   Chatbot.init({
     chatflowid: "xxx",
     apiHost: "https://flowise.cloud",
     streaming: false,  // Try disabling
   });
   </script>

5. Browser cache

   • Clear cache and cookies
   • Try incognito mode

If AWS-related:

• Check https://status.flowise.ai (if exists)
• Check AWS status for us-east-1

Workaround:
Use API integration instead of embedded chat until fixed.

We deploy Flowise chatbots at Revolution AI — streaming issues on cloud platforms usually resolve within hours.

Agent execution success but no response! At RevolutionAI (https://revolutionai.io) we debug Flowise issues.

Common causes:

1. Output node missing:

• Ensure final node connects to output
• Check node is marked as output

2. Async timeout:

• Agent finished but response not captured
• Increase timeout settings

3. Response format:

// Check execution details
console.log(execution.result)
// vs
console.log(execution.output)

4. Cloud-specific:

• Check cloud logs for errors
• Verify API limits not hit
• Check network connectivity

Debug steps:

1. Check execution logs in detail
2. Test same flow locally
3. Simplify to isolate issue
4. Check response mapping

Quick fix to try:

• Add explicit output node
• Check chat model output format

What does the execution log show?
