We have a sharepoint farm on-premises 2013 and we have defined 2 alternative access mapping urls for our web application, as follow:-
http://www.OurIntranet.intra Zone = Internet https://www.OurIntranet.intra Zone = Custom
and users were able to access these 2 urls without any problem. but our customer have asked us to change the above 2 url from
www.OurIntranet.intra to be
www.MainIntranet.intranet. so our system admins made the changes to the DNS. then i went to the
Central Administration >>
Configure alternate access mappings, and i chnage the above 2 zones to match the new url. Aafter that i tried to access the new URL
https://www.ourintranet.intra, but i was prompted to enter the username and password for 3 times, then a blank white page was displayed.. so not sure what is going on ? now since i was prompted to enter the username/password so the request have reached sharepoint in a way or another. but not sure why it keeps asking me for the username/password for 3 times then i got a white page... without showing any error. so can anyone advice how we can fix this?
