On EC2 instance I am giving wrong credentials for Basic Auth but getting 200 code and with same scenario while doing on local machine it is giving unauthorized exception

Hi @vandana_ratnaparkhi,

I'm not sure to what server you are accessing to, but looks like it's not AEM instance(which runs by default on port 4502) - unless you have configured custom port. Please check with the proper vendor to which you are trying to access server, that should solve your problem.

Hope that helps!
