I have connected to the proctor and confirmed my details related to my exam.

My proctor asked me to open the camera video, but the camera froze in between the verification process. The proctor asked me to restart my system but the same error is going on. i have try many times but not able to solve the problem, i did not aware with this error before.

than proctor told me to connect to the support for retake the exam due to this condition and problem.
