Body:
Hello,
I am running a WordPress site on Oracle Cloud Infrastructure (OCI) Free Tier in the Chuncheon region (ap-chuncheon-1), South Korea, and I am unable to connect to any WordPress.org servers from my instance.
Environment:Cloud Provider: Oracle Cloud Infrastructure (OCI)
Region: ap-chuncheon-1 (Chuncheon, South Korea)
OS: Ubuntu 22.04.5 LTS (aarch64)
WordPress: Latest version installed via GitHub mirror
Problem:
All requests to WordPress.org IP addresses (158.179.x.x) time out. This affects:
What I have verified:
Other sites work fine from the same server:
curl https://google.com → ✅ Connected
curl https://github.com → ✅ Connected
curl https://api.wordpress.org → ❌ Connection timeout
curl https://downloads.wordpress.org → ❌ Connection timeout
The issue is specific to WordPress.org IP range (158.179.x.x):
Server-side configuration is correct:
allow_url_fopen = On
WP_HTTP_BLOCK_EXTERNAL = false
WP_ACCESSIBLE_HOSTS = *.wordpress.org,*.wp.com
OCI Security List: All outbound traffic allowed (0.0.0.0/0)
No firewall rules blocking outbound connections
The issue persists across:
Multiple server instances
Multiple public IP addresses
Fresh WordPress installations
Workaround I am currently using:
Downloading plugins via PC browser and uploading manually
Installing plugins via GitHub mirror using WP-CLI
Question:
Is WordPress.org blocking certain OCI IP ranges? Has anyone else experienced this issue with OCI Chuncheon region? Is there any server-side configuration that could help resolve this?
Any help would be greatly appreciated. Thank you.
