ERROR: Cannot load some pages in iRoar View The Full Article Problem: User can log into iRoar, but some pages within it do not load. Solution: Some pages within iRoar are on nonstandard ports. What this means is that strict networks may block access to these pages and prohibit them from loading. This is most often seen when the user is trying to access the pages from a corporate network. The simplest solution is to relocate to a different network that will not block the pages. If this is not possible, use the Clemson VPN to connect to campus before accessing iRoar. The VPN client can be downloaded from cuvpn.clemson.edu.
