Hi there! I experienced it also one time .. and i'm thinking that, i'm late or the 2 minutes i think to enter the battle field is over that's why I got the "Invalid Network" error .. tho it only happened to me once when my net is suffering from so much lag .. :\

I'm not even late, happened to me more than once

What server are you currently residing in?

Burning Ash, was able to join sage last Monday. Didn't encounter invalid network. Hopefully next sage will be ok as well

Hi. I'm encountering the error again, invalid network

Todays sage and last Thursday sage

Anyone help please? How can I get advance refinement if I can't join sage all the time? -_-

I feel you T_T .. I can't enter SWB too today, it always says "INVALID NETWORK" .. T_T

Advance Refines and Summoning Points T_T ..

A screen shot for proof. if someone in oasis reads this please fix this or tell me how to fix this cause it happens to a lot

i got stuck while in battle . idk what the causes but after i accidently click esc key in battle i got stuck .

I have had this problem before, lasted about a week (3 SWB) and then it stopped.

Is the network issue still occurring on your server?

Hi there! I'm back and i just want to share what i think about this problem .. Technically, i have an idea or theory that i want to share, so we can clear or know what's the reason of this "Invalid Network" issue .. I know some of you are suffering from this issue, and the "Your Internet Connection might be slow" is not applicable because your net works great .. But, to be able to solidify this idea of mine, i need some answer :

1. Do you register your character in SWB early or late? (Early like the first 3 minutes or Late like last 3 minutes)

2. Do you use the "Automatically enter the battlefield" check box or you're entering the battlefield manually?

3. If you're entering manually, do you enter early like early as first minute or enters late like after 1 minute late from SWB opening?

Because, i think, the reason why you gets the "Invalid Network" issue is because the land that you supposedly belong is already full thus making you unable to enter the SWB .. Usually, SWB lands only have 25 slots for each land, right? (Correct me if i'm wrong) .. For example, you belong in the Lv80~89 level bracket; CrossServer 584~595 Cluster, so in that group there's only 75 players allowed to enter and in your case, you entered late and the slots are already occupied so, that's it, you will not able to enter the SWB.. I hope you guys understand what i want to explain xD.. wahahhahahaha xD ..

Did you put low lvl ninjas to register or enter sage? Or used a team with less than 4 ninja? Have seen that happening when trying to trick the system :P So try to lvl up all your ninjas to your main's lvl.

Make sure you have updated your flash and java.Also try clearing cache and flushing your dns ( go to command prompt (cmd) and type ipconfig /flushdns then press enter).
