Hotspot login "cannot send challenge response"

Users not able to login all of the sudden and getting message to enable java script, only java script is enabled. Same problem no matter what client computer or browser (IE or Firefox). Only work around so far is to enable PAP instead of CHAP but that is not a good solution. hotspot/md5.js does exist on Tik. We have not made any recent changes to Tik.

Could this be some new security from sun/java or windows? Again, it is not browser specific as we (and our clients) have tried different browsers with the same result and java script definitely is enabled.

I can only think of an error in your hotspot config.
You may want to to look over your nat entries as well as DNS name entry in the hotspot. Perhaps for all it’s worth, reset your hotspot folder.
