ok, now I got the picture at least it seem more clear to me.
so the best way to approach it is that the user you're logging in has no application access meaning it isn't on that users portal - simply do not give your user access to that application, unless it is global app and all users must be able to use it - then there is no other way if that app access isn't "routable/possible" for the users.
if this is DR device i would definitely forget about that error as it is just shouting on you that you've got "no ways" of accessing certain resources via your MAB portal. Once you see it RED you know that your "network setup" isn't working as desired.
other than that you could simply try to turn off errors via Application MAB configuration, that can be found in following settings:
Mobile Access -> Applications -> Web Applications -> Additional Settings -> Periodic Test -> tick the option OFF so the MAB won't query the App when "not working due to the network issues",
try, if that doesn't comply with your query I do not think personally that you could turn that "error" of but I might be wrong. Some other guys here may be off assistance just in case ...
hope it helps
