Aliexpress problem, Oh no! The Internet is not working.

i have been facing this problem while placing my order on aliexpress for last two days and their help never replies. My internet is definitely working. Has anyone encountered this problem on aliexpress before ? is there any solution? someone in a public forum somewhere suggested to change browser, i am using chrome browser, i tried other browsers as well like opera, epic, chromium... nothing worked.
