I have seen this issue once before but I did not document it or log the error and have it reported. Normally I understand stuff happens and maybe things just "fall off", however, adding the layer back in is only a small piece of what I now have to do to get my map up and running again as I had build custom pop up displays for this map and its features.
As I open up my map I notice nothing of out of the ordinary ... [ATTACH=CONFIG]11121[/ATTACH]
and then when I go to expand my layers, I notice a major problem .. [ATTACH=CONFIG]11122[/ATTACH]
My map is missing the layer that was attached to it from a websource, which by the way, is working just fine and I have found no errors trying to reuse that source. [ATTACH=CONFIG]11123[/ATTACH] [ATTACH=CONFIG]11124[/ATTACH] http://maps.dot.state.tx.us/ArcGIS/rest/services/CoordSysZones/MapServer
I attempted to share the link with another staff member in my office and when I tried to open it up, I kept getting the error that I needed to relog in due to some administrator change. The process would keep looping where I tried to open the link, it would open for a few seconds and then go to a logon screen or give me the admin change logon request. Link: http://bit.ly/v2RyE3
So I have a couple of things here ... What could have caused this problem to have happened? Is it just a glitch and we just deal with it and rebuild? Did I fail to do something I should have? I had no problems with this map nor did any users have any issues until today.
next thing is, obviously the link somehow broke, however, after spending time building my pop-up windows for my features, why is there not a way to just "repair" the link? Is this something perhaps we may see in the near future?
If you look at the item details of your map, you'll notice the URLs to the layers say "services.arcgisonline.com..."
You need to share those services with the people you want to see the map. Otherwise, when they open the map, they won't have access to the services. Typically, if you are not signed in you will be prompted to sign in. If you already are signed in, you will just not have access to the service and you'll get the error message you see.
Were you thinking that you were actually accessing the services referenced in your ArcGIS Server?
