Suddenly Can't Access Your WordPress Admin? 403 Forbidden Error Resolver (Domestic Access Issues)

One day, I went to the admin page to write a blog post as usual.

But...
A strange message appeared in front of me.

403 Forbidden - You don't have permission to access this resource.

“...What is it? Did I touch something wrong?”
“I was fine until yesterday, what's wrong?”

At first, I was confused - I hadn't installed a new plugin or changed themes.
My hosting was working fine with Cafe24, and I don't remember doing anything that would have gotten me in trouble.

But I can't access the admin page...
My mind is blank... and my blog, Mystery Days, feels locked. 🥺

🧩 The cause was surprisingly simple

Cafe24“s security setting of ”Allow access from within the country only".
This was the problem.

I would definitely use the I was connecting from Korea., The IP was also a domestic IP...
If the Cafe24 server is My connection was misinterpreted as ‘coming from abroadYou've done it.

Why is this happening?

• Some carriers (especially mobile LTE/5G and school/work Wi-Fi) can make IP routes look overseas
• If you're using Cloudflare, CDN, etc. your IP might be seen through a proxy.
• The server-side IP database might be outdated and inaccurate

Eventually, I decided to use I'm in Korea, but I'm blocked as a ‘foreigner’You've been tricked. 😢 .
(Sorry, buddy...)

💡 FYI, this can happen to you too

Situation	Cause
Blocked even if you're in the country	IP mistaken for international (proxy, telco, CDN, etc.)
Admin-only access denied	WAF/ModSecurity blocks wp-admin
Suppressing only some images	Hotlink protection or path errors
You can't rename plugins	Security module is fully blocked

🔧 Bonus Tip - If you have the same problem, try this!

• .htaccess Reset after backing up files (to WordPress default settings)
• Disable security plugins (Wordfence, etc.)
• Clear browser cache when attempting to access the admin page
• FTP to access the wp-content/pluginsDisable weird plugins from your site for a while
• If that doesn't work, use the Contact Cafe24 Support to ask if ModSecurity is blocked!
