If you are using QQ Browser, after the firewall is successfully set up, some websites cannot be opened in QQ Browser, such as Youtube can be opened but Facebook cannot be opened, or some other websites can be viewed but some cannot be viewed.
As shown in the figure below:
You can solve this problem by modifying some options in the QQ Browser settings
The specific steps are as follows:
1. Click the three horizontal lines icon in the upper right corner of QQ Browser to enter the menu bar
This tutorial takes the 10.4 version of QQ Browser as an example. The display position of the three horizontal lines icon may be different in different versions, but the specific steps are the same.
2. Click the settings icon
3. Select the security settings bar and uncheck the three options of "Website Security Cloud Detection", "Website Record Information Cloud Detection", and "Download Cloud Detection"
After unchecking, it will take effect automatically
At this time, if you revisit the website you just couldn't open, you should be able to access it normally!
We still recommend that users use Google Chrome browser with LetsVPN, which will not have the somewhat inexplicable interference problem similar to QQ Browser.
