Hi @Naveen Chandra Sekhara , this seems to be a pretty common issue with Jenkins. However based on your thread it looks like you've exhausted most of the options suggested to you. Have you had a look at this SO thread? Most likely you have, but if not please try these solutions. The nature of your error messages make me lean towards this being an issue with the Jenkins setup and not Azure, which means your solution most likely lies there. However, if you feel as if you have exhausted all options please let me know. I can set you up with a free Azure support ticket so we can see if there's something broken on our end.
Best,
James
