403 Error Triggered by Litespeed and Safari

I have faced an annoying 403 errors after updating one of my client website litespeed plugin.

After the latest update of litespeed, I realized that 403 error always happen.
At first, i do not any have idea why this happen and ask for help from my hosting service provider

After long investigation myself, I realized that the error is trigged by litespeed when the users using safari.

Here are the tests that I have go through.

403 Error test

1. Litespeed on, iOS device > trigger 403 error
2. Litespeed on, Android device > normal,  no 403 error
3. Litespeed off,  iOS device > normal,  no 403 error
4. Litespeed off,  Android device > normal,  no 403 error

Once 403 error is triggered:
- All the devices in the same network show 403 error, including IOS and Android devices
- All the websites in the same hosting show 403 error, including all my other websites in the same host.
- Need to wait about 10-15mins to become normal again.

Devices tested that trigger 403 error : (using safari)
- iPad , Iphone 13, Iphone 7

Tested devices that do not trigger 403 error : (using chrome)
    - Imac, Android mobile phone

Now, I have deleted litespeed cache used another cache plugin, all the 403 errors gone.

For me, the problem is solved now, but I still create this post because there might be some other people having the same problem like me.

They can take this as a reference.
