FLASK

[arinapo]

Good afternoon,

I have been trying to run the bubble application chat, and I have been constantly receiving the issues. I have tried to fix it by different ways, but none of them seemed to work. I assume it is a flask application that is not running on my VM. Could you please assist me on this point? P.S: All security settings are enabled

the flask application allows CORS so the backend should not be the problem here.

• try to open this Bubble on your phone browser and see if it works there.
• does curl from terminal work fine?

Check the port number perhaps. "err::connection refused" suggests that the server is denying the request because of a firewall config.

Sid just tested your server and it looks like the docker is not working as expected. You’ll need to fix something in the docker, probably about the way it is deployed (there should be no changes to the code).

Here is the error message. The last part indicates that the output from the hugging face model is “null” which is not being handled well. Actually it sort of doesn’t matter, because as long as you didn’t change the docker code, there is something wrong with the way the docker is deployed. You may need to try deploying the docker from scratch.

When you deploy your docker again, test it first using curl, before attempting to connect to it from the front-end.
