Hi, I am totally new to Rasa and trying to use the Rasa Chat widget described [here](https://rasa.com/docs/rasa/connectors/your-own-website/#chat-widget)

I get this error [http://localhost/socket.io/?EIO=4&transport=polling&t=NttRrl2](http://localhost/socket.io/?EIO=4&transport=polling&t=NttRrl2) net::ERR\_CONNECTION\_REFUSED

Hi @rafa21 and welcome to the forum 🙂

No worries will solve this together. Please can you share your `rasa --version`.

@rafa21 can you please update this “[http://localhost:5005](http://localhost:5005)”

@rafa21 are you using rasa open-source or rasa x? It local installation or server-side?

@rafa21 which command you are using to run the rasa?

Dear @nik202Thank you so much for your help

> Rasa Version : 3.0.3 Minimum Compatible Version: 3.0.0 Rasa SDK Version : 3.0.2 Rasa X Version : None Python Version : 3.8.8 Operating System : macOS-10.14.6-x86\_64-i386-64bit

I am running rasa as:

> rasa run -m models --enable-api --cors “\*”

And using Flask for the web.

I had tried changing port and I get: rasa-chat:2 GET [http://localhost:5005/socket.io/?EIO=4&transport=polling&t=NtyrcHo](http://localhost:5005/socket.io/?EIO=4&transport=polling&t=NtyrcHo) 500 (Internal Server Error)

And on the rasa console I now get:

@nik202 I wonder if the problem is my flask code:

```auto
from flask import Flask, render_template, request, jsonify
import os,sys,requests, json
from random import randint
app = Flask( __name__ )
@app.route('/')
def home():
  return render_template('index.html')

@app.route('/parse',methods=['POST', 'GET'] )
def extract():
  text=str(request.form.get('value1'))
  payload = json.dumps({"sender": "Rasa","message": text})
  headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
  response = requests.request("POST", url="http://localhost:5005/webhooks/rest/webhook", headers=headers, data=payload)
  response=response.json()
  resp=[]
  for i in range(len(response)):
    try:
      resp.append(response[i]['text'])
    except:
      continue
  result=resp
  return render_template('index.html', result=result,text=text)
if __name__ == " __main__":
  app.run(debug=True)

```

@rafa21 No this is not related to flask this is much related to socketIO and Sanic version issue.

Can you please see this thread [Rasa 3.0 error socket.io - #13 by nik202](http://forum.rasa.com/t/rasa-3-0-error-socket-io/50061/13) and try update the versions for the mention packages, please take care of all the dependencies issue (red color) some can be rasa-sdk and some can be sanic.

@rafa21 If you still face some issue please let me know please.

**Trick Suggested to check your code:**

If you think that you have some issue with flask, you can create the new rasa environment and try install rasa and rasa-sdk to 2.8.1 respectively and then try run the rasa and flask. You will get the clear result. [_please don’t perform this suggestion in current working environment for that please follow the above mention thread and suggestion_] Thanks.

I wish this will solve your issue as earliest.

Dear @nik202I tried following your instructions and update all the list according to requirements, but according to pi some are incompatible. I added it in your other thread:

> [@Rasa 3.0 error socket.io](http://forum.rasa.com/t/rasa-3-0-error-socket-io/50061/28):
>
> Hi @nik202 The versions you list seem to be incompatible according to pip: rasa 3.0.2 requires sanic-routing\<0.8.0,\>=0.7.2, but you have sanic-routing 0.7.0 which is incompatible. sanic 21.6.0 requires sanic-routing==0.7.0, but you have sanic-routing 0.7.2 which is incompatible. When I run pip install sanic==21.6.0 Sanic-Cors==1.0.0 sanic-jwt==1.7.0 sanic-plugin-toolkit==1.2.0 Sanic-Plugins-Framework==0.9.5 sanic-routing==0.7.0 I get ERROR: Cannot install sanic-cors==1.0.0, sanic-plugin-t…

I tried doing

```auto
pip uninstall rasa
pip install rasa==3.0.2

```

but I stll get

```auto

@rafa21 Great Rafal 👍 Can you share the rasa current version and all related packages with version for the other readers.

Please can you update the topic category to rasa open source from Getting started with rasa.

Thanks. Nik

Hi @nik202

Thanks for your help To go down the Rasa version I had to uninstall the one I had, and all the sanic libraries, then reinstall with the --use-deprecated=legacy-resolver option

Now that it works, I am now using:

```auto
Rasa Version : 3.0.2
Minimum Compatible Version: 3.0.0
Rasa SDK Version : 3.0.2
Rasa X Version : None
Python Version : 3.8.8

```

```auto
sanic 21.6.0
Sanic-Cors 1.0.0
sanic-jwt 1.7.0
sanic-plugin-toolkit 1.2.0
Sanic-Plugins-Framework 0.9.5
sanic-routing 0.7.0

```
