[Error] Message: Internal curl error has occurred within the executor! Error Number: 28

I am running a self-hosted Appwrite instance on a lab. I am running it into an Ubuntu server, using CloudFlare for DNS, I followed the documentation on https://appwrite.io/docs/advanced/self-hosting/installation. I deployed the Starter Function but I get this error on Appwrite console: Internal curl error has occurred within the executor! Error Number: 28\nError Code: 500 I looked on openruntimes-executor container and I saw this error:

[Error] Type: Exception
[Error] Message: Internal curl error has occurred within the executor! Error Number: 28
[Error] File: /usr/local/src/Executor/Runner/Docker.php
[Error] Line: 1145

My .env file is a copy of this and the docker-compose.yml file is a copy of (this)[https://appwrite.io/install/compose], the lack of information about this error is giving me a clue that I might be doing something wrong but not sure where, I really will appreaciate any help/clue to fix this error.

I am using appwrite 1.7.4 (has the docker-compose.yml shows)

I fixed it, I was doing something wrong, my server was created to point a domain A but my Appwrite instance I wanted to point ot domain B, that inconsistency was doing the executor point to a public IP while resolving hostname on curl http://hostname:3000, to fix it, I had to update the searchdomain:domain_B.LTD on network configuration file, that files is in different places depending on the OS (mine was in a atypical place because I was virtualizing), once you make that change, you should be good.
