[HTTP Code = 403] (APNX-1-4279-001)

Hi all,

when I am using one of the actions from my tempo I am able to open the action but when I try to enter some data in the fields I am seeing an error message [HTTP Code = 403] (APNX-1-4279-001).

This is happening only when I try to login with users from specific groups that we added recently and It is working fine for old groups. any one faced similar issue? 

Any help can be appreciated. Thanks in advance.
