Hi @Gurvak_Singh! Thank you for your reply!
I am happy to hear you have gotten DevKinsta back into a running state. But, I am sorry to hear you are continuing to experience the issue where you are not prompted to update the hosts file when creating a site.
I have looked into this further and I have found a thread where another user had a similar issue. It turned out to be related to AdBlocking software installed on the system. A link to their post can be found here: Host file update failed DK0022 (authorization never requested) [Mac] - #4 by phil-s
To clarify, do you have any AdBlock software installed that may have modified the hosts ffile? If so, could you please try making a backup of the hosts file, and then resetting the hosts file to a default state?
Please let us know if this helps! We look forward to hearing from you!
