Function Failed host lookup

as the title suggest, my function cannot look up to my appwrite console. it's just giving me error

Exception: AppwriteException: , Failed host lookup: 'my.domain.tech' (0)
#0      main (package:account/main.dart:144)
<asynchronous suspension>
#1      Future.any.onValue (dart:async/future.dart:608)
<asynchronous suspension>

tried running docker ps -a command to see what's error, and all seems running good

does that domain name work?

Yes, the domain name is working correctly

something is screwing up your dns records. try doing a curl from inside the runtime container

and on your server

How do I do it?

found it tried curl my.domain.tech its saying could not resolve host

tried it in my server, it gets an error but trying it outside my server it doesn't give an error

tried it in my server
What do you mean?

check your /etc/hosts to see if something weird is being done with your domain routing.

either that or maybe firewall

What do you mean?
I connected to my server using ssh command and then I used curl inside it but it returns could not resolve host

check your /etc/hosts
I have not changed anything in my hosts file but this is the result when checking the file

GNU nano 6.2
/etc/hosts
Your system has configured 'manage_etc_hosts' as True.
As a result, if you wish for changes to this file to persist
then you will need to either
a.) make changes to the master file in /etc/cloud/templates/hosts.debian . tmp1
b.) change or remove the value of 'manage_etc_hosts' in
/etc/cloud/cloud.cfg or cloud—config from user—data

either that or maybe firewall
I have setup a firewall to only allow inbound connection of ssh port 22 and https port 443 while the outbound rules are :

I could ping my server inside the ssh terminal, but on the outside it returns Request timed out. this was supposed to be working a few weeks ago

kinda weird why is it acting this way

Ok so if you can't curl from your server (not even inside the container) it definitely won't work in the container

Maybe it's an ipv6 problem?

Or maybe the DNS server your server is using is different/special?

I have a question, I set my _APP_DOMAIN_FUNCTIONS=functions.mydomain.tech and I setup my digitalocean networking Type A to *.functions.mydomain.tech with the value of my digitalocean droplet, is this correct?

You should be using a cname record pointing to your main domain.

This shouldnt cause this problem though
