Trouble logging in from different computer

When I’m on the computer at work and try to log into Internachi it just sits there spinning. No trouble logging on a home. Any ideas what it might be?

I had to look up the internachi forum on google and could log on to that.

Your employer found you out and has blocked InterNachi from loading.
You are supposed to be working, not using your employers resources to ‘get another job’!
