When trying to run function (which also run successfully from local machine) in Appwrite self-hosted instance on 1.5.7 and Node 18 runtime (picked 18 after trying on 21 and finding out about this issue - https://github.com/appwrite/appwrite/issues/8311) and on the listDocuments call (first line of code in the function basically, nothing else is going on) I get fetch failed error with the following stack. Function runs 12 seconds before failing (time limit is maxed in settings).

`TypeError: fetch failed

Node 21 and Node 18 runtimes behaved absolutely the same.

What it could be?

After experimenting with endpoints & DNS settings, indeed the issue is on endpoint - function worked when I specified proxied/tunneled via Cloudflare domain name and didn't work with 'A' record subdomain. I'm not an expert in this topic - are there best practices for appwrite functions? If I have simple self hosted instance and I use single domain for everything, should I connect to appwrite from functions via public domain name, localhost, other? Thanks!
