Unable to access Wordpress API and Plugins API on OpenBSD 7.3

Question

I just finished setup my web server on OpenBSD 7.3 by installing php-7.4, nginx, and MariaDB. the Wordpress admin looks fine but when i check the debugging, it show several error like this:

GET http://d2salfytceyqoe.cloudfront.net/wpml33-products.json
http_request_failed

POST https://api.wordpress.org/plugins/update-check/1.1/
http_request_failed

POST http://139.180.143.200/wp-cron.php?doing_wp_cron=1681964903.0030410289764404296875
error getting response code, most likely a stopped request

I assume somehow OpenBSD blocked them, but when i check it by nslookup it working fine

nslookup api.wordpress.org
Server:         108.61.10.10
Address:        108.61.10.10#53

Non-authoritative answer:
Name:   api.wordpress.org
Address: 198.143.164.251

another problem is when i change my default url site from my server ip to my domain it just giving me error. i check the logs nothing found, i set my nginx correctly and i check my domain with https://dnschecker.org/ it point out to my server ip. Any help please?

In OpenBSD, https runs Wordpress within chroot. So the chroot blocks access to services like DNS. You need to copy the config files inside the chroot:

mkdir -p /var/www/etc
cp /etc/resolv.conf /var/www/etc
cp /etc/hosts /var/www/etc

In my case, I had to add the nameservers to resolv.conf:

nameserver 1.1.1.1
nameserver 9.9.9.9
