I just got a new router. I set up LAN preview in C2 according to Ashley's guide. Everything worked fine; previewed in all browsers, previewed to my mobile.
Now...it isn't working. I haven't changed anything that I can think of. This is the error I'm getting:
I am running C2 as an administrator. I've double checked this. I'm using r190 stable. I also tried a separate instal of r192 beta, same thing.
Any ideas where to start here?
