I am building the rasa chatbot and trying to deploy it on messaging platforms like slack,telegram. The bot is working perfectly fine if I use ngrok for tunneling from my laptop onto slack. But when I deploy the same chatbot onto my server and run it, it returns with asyncio - Unclosed client session error. For clarification, the server has a public url and i am able to do curl check onto it: ![rasa2](https://europe1.discourse-cdn.com/flex013/uploads/rasa/original/2X/0/093af8d4a5f610d6b8630299579282dcb35d701e.png) It works Also, the slack app installer has accepted my webhook url: ![rasa1](https://europe1.discourse-cdn.com/flex013/uploads/rasa/original/2X/2/2c14b4a34d56ecceae98c5a2e3886790a2f3d749.png) But as soon as I send the text, it gives error in debug logs as : **LOGS** 2020-06-11 06:34:22 DEBUG rasa.core.tracker\_store -

Received retry #1 request from slack due to http\_timeout. **LOGS END** Please help me out. The same error comes up when I deploy this on telegram that means there is not problem with a particular connector, Also, one strange thing is that when I run a tunneling tool ie ngrok on my server machine and use that to deploy the bot on slack, it again starts working as normal. Any help would be appreciated. ---

Hello @pushkarpb, Welcome to our community! 🥂 I did some research and this doesn’t seem to be a problem (or should be one). If you could provide a virtual environment (or another way) with the simulation I can try to debug, fix, and submit a PR to RASA, if it is really a problem. Cya! ---

Hi @lluchini, Thanks for offering your help. If its okay, we can get on a zoom call or something on Monday and look at it together? You can send across email id if you want to sync up offline. ---

Hey @pushkarpb, sure we can get on a call, no prob, but if you could provide you an environment for download I could try here before we get on a call, so I’ll have a baseline to discuss with you. You don’t need to include your project files (nlu, domain, credentials), I can use mine and see if it’s a problem on environment ou something linked with you project, then we start 4 hands debug, what do you think? Either way, contact me trought linkedin (it’s on my profile) and we continue from there, and after we solve this, we can post back here to help others. Cya!
