Hi @Aparna, Checked with following three use cases: 1. If 'Credential validation was not successful: execution expired' then button should not get enabled (Working as expected) 2. With wrong user/pass/url, validation should not be done and button should not be enabled (Working as expected) 3. If 'Credential validation successful' then button should be enabled (Working as expected) Validation is working fine with all of the use cases. Verified on: 5.9.0.1.20171004215954_13427ce (also on 5.9.0.2.20171010190026_0413a06) Great fix @Aparna! -Thanks!
