I realized that by manually solving the recaptchas on the site, the same error occurs and the recaptcha you resolve is not accepted and the page reloads.
I already requested the refund days ago and it is being processed. I used free proxies, but they are of very low quality, and I don't want to spend a lot on it.
These are the first days of use and I am facing this problem, I am using capmonster together with openbullet (anomaly). At no time was I told that I should have to buy proxies, and I've already asked for a refund because I'm not able to use it.
