Yes, thanks to both of you.

I don't know if it will be possible, anyway, I already have my own domain and servers running, and I'm just stuck on these 2 problems, the first problem is that I can't go to other grids from my grid, but from the other grids you can enter my grid, and the second problem is that I don't know how to put the correct login uri, because I put the correct login uri but on the diva wifi page it appears as localhost:9000 but that is not the correct one, and I have given it a and again and again the opensim guide and I can't find how to solve these 2 problems since I have done everything as the guide, but apparently I have done something wrong, since those 2 things fail

You have 2 outworldz sims posted at your profile....
I'm not sure - It is possible to use outworldz.net domain name without outworldz specific windows only software????

Why cant people, who post here for help, ever reply if this helped or not, or if problem is solved?? This also causes that no one wants to help anymore. A matter of fairness!

There is 3 possible reason for this:
1. You have wrong DNS records and/or router settings. https://opensimworld.com/post/95832
2. You have wrong config files about IP address and DNS name.
3. If you cannot visit onlu some grids then may be.... Too many grids bann small grids and you receive this.

By your profile you run outworldz grid. So some specific settings. It is best to contact Ferd for problems. Standard opensim software is diffrent.
