Few more possibilites
1. Check in SMICM the HTTP port maintained is 8080.
2. Test someother service in SICF check what it displays?
3. Try with the same link with IP Address of vcomp006.
(if this works, then it could be because, the host file entry needs to be maintained)
4.** worst case scenario - try SAP_ALL and try opening SOAMANAGER, just to make sure its not got to do with a missing authorization.
