Can not access Office Router after RT N66U upgrade

[rirusssma]

I was able to remotely access the Router in my office from my Home where I use a RT-N66U.
After I upgraded the firmware on my home router to 3.0.0.4_376.48_3 the office router is not accessible using (office IP) 2.1.1.1:8080. I get "This web page is not accessible"

Any suggestions?

Thanks.

PS: I do have cameras at the Office and I can access them with no problem. The ROUTER, however, is not accessible using :8080
