Right now the server for the check is broken. If the question mark does not disappear after it is fixed, you may have to allow http://ping.manjaro.org in your PI. Or disable it, if you do not connect your laptop in hotels, cafes, airports etc. places using captive portals.
p.s. several hours later - server should again be up. Although the status page still does report problem
p.p.s. broke again. Well, we will just wait a little more.
