Can't Host / Can't Connect to and Other Common Fixes


  1. You must allow ports 6112-6119 TCP and UDP out and in, through all firewalls! - MOST COMMON PROBLEM!
    -Linksys Port Forwarding
    -Netgear Port Forwarding
    -D-Link Port Forwarding
    -Windows XP Firewall (comes from SP2)
    • Go to Start > Control Panel > Security Center > Windows Firewall
    • Either go to the Exceptions tab and allow the ports, or turn the firewall off.
    -Zonealarm Port Forwarding
    -Blizzard's Firewalls and Hosting Games Thread
    -Blizzard's General Port Forwarding Page
    -TH Guide - Firewalls and Hosting on -by SD_Ryoko
    -Port List of Routers
  2. Do you have multiple computers using the same external IP address (LAN)?
    • You must use ports consecutively to allow this to work.
    • For example: You have internal IPs of and
    • The first IP would need port 6112, the next IP would need port 6113.
  3. Make sure to install all current patches. If you cannot download from, here is a list:
  4. Reinstall

  1. Reduce the problem to the router or computer (do each step separately):
    -Connect MODEM directly to computer, test.
    -Turn OFF all software related to firewalls, test.
  2. Make sure your modem doesn't include an internal router/firewall. Research this information before posting.
  3. Check the Options menu in the game to make sure the port number matches the port you are forwarding.
  4. Use a static IP address (prevents the internal IP address from changing).

Fixes/Information for other common problems:

I've done this already, and when the new patch came out for TFT, I couldn't host anymore. I haven't tried to re-forward the ports because I forget the admin/password and my father won't tell me (you're just going to give it more viruses :nuts: ). My question is this: what was in that patch that goofied up my hosting capabilities?
Re-Apply a firewall rule for ports 6112-6119 TCP and UDP.
Sometimes a new game version or new software version messes the rule up.

If you're still having problems after that, please post a new thread, since this is for suggesting other fixes to common problems that are not on the list already.

there are some of us out there with NAT translation from out ISPs, so we can not make it work no matter what we forward, just a heads up :(


Is it possible to host while connected to a wireless router? I can put the cable right in the back of my laptop but i have to be at the family computer. I heard you were unable to host while connected to wireless internet is this a fact or is it possible to host?


It is possible to host, but seeing as wireless is not a constant connection, you will usually lag off and on randomly while hosting. It is better to have a wired connection when hosting, because the connection is constant.

when you say that, do you mean download as in when your connecting to and it says "downloading update"?

I know thats probably a stupid question, but I just want to make sure Im right with all this so I can host my games.


Yes, because sometimes doing it manually (downloading off of blizzards website instead of can resolve some known issues.

Your Help (For ONe Guy)

Hey, Uh, To THe Guy With The "Can't Validate" Thingy, I Had That Problem Before, You May Have Deleted Something Important THat Made It Happen. The Solution Is To UNinstall And Then Reinstall Warcraft 3, And I Mean ENTIRELY (Though When It Asks To Keep THings You Can KEep THem). That Should Bring The Deleted Thingt Back And Fix The PRoblem.


hej do you have resolved your problem if you have please tell me how becouse I have the same problem.

ihave reinstaled more the 20 times and it didnot work its still says cant validate version

    they did not winterize any of the plants and they froze
  • The Helper The Helper:
    it is not that power consumption went up it was available capacity went down with power plants freezing
  • Varine Varine:
    What a fucking disaster. Are all of the Texas people okay? I see TH is, are we the only two?
  • Varine Varine:
    How have the other states held up? I just got power back so I have no idea what's going on, we didn't get warning
  • Varine Varine:
    Why the fuck didn't they fix this ten years ago when it happened?
  • Blackveiled Blackveiled:
    I'm in it with you and TH as well. My power has been in and out, and I have a ruptured pipe that I need to fix, shouldn't be too bad to fix myself.
  • Varine Varine:
    I hope you're staying warm! Apparently the supply is coming up so hopefully we can get back to normal power soon, mine has been on for six hours now.
  • M Mulciberxp:
    My power has been off most of the last 2 days. We had a generator installed 3 years ago though, so we're staying warm. Water is another issue...
  • The Helper The Helper:
    Where I live has a pool so we are using that to get water to flush the toilets. We have enough bottled water to drink and brush teeth and stuff but it has been a few days and no shower though....
  • Varine Varine:
    I had some water in gallon jugs, and got our water back on yesterday. We don't seem to have any leaks, but I haven't crawled down there to look yet.
  • The Helper The Helper:
    still no water I cannot remember when I last showered now I know how they felt in the old west lol
  • Varine Varine:
    My poor plants are happy, they aren
  • Varine Varine:
    aren't used to going this long without water or lights or normal heat. I think a couple of them froze, but they look like they'll make it
  • Varine Varine:
    Well one of them is pretty rough but I think it was sick to begin with, that one always had some problems.

    a positive could come out of this. So many people trapped at home could put a dent in the covid numbers in Texas
  • Varine Varine:
    That dude, Tom Boyd, is really upset about the backlash from his "it's your fault you're freezing" thing because he claims he resigned before saying it, so it wasn't like he said it in his official capacity or anything.
  • jonas jonas:
    Almost as if he was saying "screw you guys, I'm going home"
  • Varine Varine:
    I'm fairly new here still but that seems to be the analogous message by several of our politicians.
