Why this error after trying to remake this API config in OB2

I keeping seeing this response after trying to remake this API config from OB1 to OB2. what could be the cause ? any help ?

There’s a captcha challenge to solve, maybe the site detected something suspicious in your headers or IP? Try to use a proxy or vpn and see what happens.

It worked now but when i run it under jobs after few checks it seems not working again and if i try to check config i see this same screen … what could be the cause ? any help?

Are you actually using proxies in your job?

@Ruri Yes am using proxies.
