Can you check the file through crxde whether its been replicated to publish from author or not. If it's present there then you should. be able to access the file directly from publish server.Are you seeing this issue with dispatcher?

@gspatil11 Few questions-1. Is it a fresh instance2. If not have you made any changes to trustore or keystore try to recreate the truststore and keystore.

Could you please explain bit more what exactly you are trying to achieve?

No it wont, rest i don't see any other option as far as i know.

You need to achieve this through css.Let entire page width be 1300 and stretch header and footer to full width like below- @media screen and (min-width: 940px).fullwidth {left: 50% !important;margin-left: -50vw !important;position: relative !important;width: 100vw !important;}
