Hello Anil Patel!
We completely understand you, and we are trying our best to resolve your issue. If you have an enterprise license key, please contact directly your personal ZAPTEST manager.
As for community edition, we cannot emulate your issue in our lab, and so on we need your help to resolve the problem:
1. Do you use any proxy servers? Could you try to disable them or check configuration?
2. Could you try to change your password on our website: try to set up a “simple” password (only for checking the issue), probably some firewall or traffic inspector cannot translate some symbols. Please don’t forget to change your password back (to a strong one).
Thank you,
ZAPTEST Team
