@federicotdn This is a continuation of the issue I showed you yesterday, where the action server was not replying. I think it's because nginx is crashing

Thanks for raising this issue, @JustinaPetr will get back to you about it soon✨

Please also check out the docs and the forum in case your issue was raised there too 🤗

Hey @cristianmtr, I think this might be a problem with how the nginx config is generated. The correct values to use would be the URLs defined in RASA_X_HOST and RASA_PRODUCTION_HOST without the http:// prefix. Is it possible to override the env value for these two variables in your Dockerrun.aws.json file, only for the nginx container? (note that RASA_X_WORKER is not relevant here)

[cristianmtr]

Yep, that did it. Thanks :+1:

I've created an issue for this on the Rasa X repo. Thanks for bringing this up :+1: Feel free to close the issue if it's working correctly.
