CS1.6 is not a "status"
Regardless of this, i don't know any version of half-life where this error occurred.
At last you could try to set the real IP instead of the hostname. If it is only a DNS problem, so he cannot dissolve the url to an IP and therefore uses the server-ip instead.
Code:
sv_downloadurl "http://198.38.82.159/cstrike/"
