ReverseProxies OCR ERROR

I set ReverseProxies on 2nd captcha services but it show this error all time.

I check user and pass is OK.

I ask ReverseProxies support ... he said GSA SER error not ReverseProxies Error.

please help me to fix it.

best regards,

Yes had the same problem before so I set up the service inside CB and it's been alright so far..

You can't fix this. It's happening when GSA sends them an image that is not a captcha.
