Hi,

Try to add these directives :

ModPagespeedDomain *.newsys.in
ModPagespeedLoadFromFile "https://www.newsys.in" \
                         "/var/www/path"

Configuring ModPagespeedLoadFromFile may resolve the problem by either speeding up the transient "deadline expired" messages or working around any problems in the http(s) fetching paths. But it you configure direct file loading from the web root, you need to check if you need to restrict direct loading, to avoid exposing sensitive files. 

See "Limiting Direct Loading" at https://modpagespeed.com/doc/domains#limiting-load-from-file

Also it's not necessarily a problem that you receive a 'deadline exceeded' message, and perhaps that message sound unnecessarily harsh.

It's just indicating that an optimization is occurring in the background, to avoid further delay delivering HTML to the client.

This is only a problem if every time you refresh the page, that message keeps showing up.  If this is the case, there might be something wrong with your cache.  Could you check the Apache logs to see if mod_pagespeed is printing error messages?

LoadFromFile might be a workaround for extend_cache, but not for image optimization.
