Why Is CurseForge Not Opening?
When CurseForge refuses to start, it’s usually due to one of these causes:
-
Corrupted installation files after an update or crash
-
Outdated Overwolf client, which CurseForge relies on
-
Firewall or antivirus conflicts blocking the launcher
-
Low system resources preventing it from starting
-
Internet connectivity issues disrupting login or updates
-
Regional restrictions that block access in certain countries
IP Restrictions: Can You Access CurseForge Everywhere?
While CurseForge is widely available, some users report that the platform is inaccessible in certain regions due to IP-based restrictions or local internet regulations. This means that if you are in a country with limited access, the launcher may not open properly or might fail to connect to servers.
Where You Can Access CurseForge Freely
-
United States
-
Canada
-
Most of Europe
-
Australia
-
South Korea & Japan
Where Access May Be Limited or Blocked
-
Middle Eastern countries with strict content controls
-
China (most modding platforms are heavily restricted)
-
Certain regions in Russia
If you suspect your IP address is being blocked, one solution is to use a reliable free proxy VPN in UFO VPN. By switching to a server in an accessible country, you can bypass regional restrictions and ensure CurseForge runs smoothly. For example, connecting to servers in the US or Western Europe usually restores full access.
