Council Of Architecture — difficulty in writing online nata exam

Today 29 august 2020, when i log into the secure browser (The application or software provided for writing nata exam) the question paper did not appeared on the screen. Instead the screen showed "please wait". The next moment i called for query and the proctor asked me to restart the system and to check my internet connection. The system has showed the network speed of 1.99 mbps. When i restarted the application appeared completely blank. Again i contacted the proctor and asked me to wait for few minutes. After when i login, the first session was over. The proctor told me to call the supervisor, but there was no reply. Later i was asked to attend the second session but the condition was same. So, i was not able to write the exam which was only hope. Kindly make a solution for writting the exam as soon as possible.
