0% success rate of popular captcha services (2captcha / captcha.guru / capmonster.cloud)
I've using CB for a long time but recently I run into some wired situation,
1. 0% success rate of 2captcha, captcha.guru, and capmonster.clou


note: captcha.guru solves image captcha so all the success is image captcha.
2. In CB, captcha.guru, and capmonster.cloud seems down forever.

But, I checked their website, everything is up and running.
It's very bothering me to decide which service I should stick with.
I set my CB to run on local IP like 192.168.x.x. Is there anything I should config in CB or my system.
Thanks,

Key is entred in setting, but the success ratio is too low, is it normal?
