OCR server issue

TestComplete uses a web service residing at ocr.api.dev.smartbear.com, which uses Google Vision API. It sends images to the service and obtains the text recognition results. The computer, on which your tests run, must have access to the web service. If you have firewalls or proxies running in your network this can cause issues.

If you enter https://ocr.api.dev.smartbear.com in your browser, it should open Swagger i.e. SmartBear OCR API, and if you get an invalid response, then the service could be down.

You can get more information at https://support.smartbear.com/testcomplete/docs/testing-with/object-identification/ocr/requirements.html , and also see post OCR service failed. request contains invalid argument | SmartBear Community
