Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Steamworks server browser "Failed to respond"

Hello all,

I'm at my wits end with this problem that has already tried to derail my project. No one seems to have any solution and no one seems to have encountered this, so Epic devs and others alike, please help.

I'm trying to setup a server browser with Steamworks and the OnlineSubsystem. Everything works great under LAN, but when tested with my friend in another continent, no sessions are found.

At first we were using the GameServer API (bUsesPresence=false) and we got these messages:

 [2015.07.27-22.02.54:509][931]LogOnline:Display: STEAM:  "gamedir" "boxmanbegins" 
 [2015.07.27-22.02.56:992][ 80]LogOnline:Display: STEAM: Failed to respond IP:MYFRIENDSIP
 [2015.07.27-22.02.56:992][ 80]LogOnline:Display: STEAM: Server query complete '0' eServerResponded (Server success)

Then we started using the Lobby system (bUsesPresence=true) and had no luck again, getting these messages in the log.

 [2015.07.28-21.22.41:560][113]LogOnline:Display: STEAM: Starting search for Internet games...
 [2015.07.28-21.22.42:043][142]LogOnline:Display: STEAM: Found 0 lobbies, finalizing the search

We then tried to direct connect using the console command open MYFRIENDSIP and even that didn't work. We got this message:

 [2015.07.28-21.26.08:505][522]LogNet: Browse: MYFRIENDSIP//Game/BoxmanBegins/Maps/BMFrontEnd

 [2015.07.28-21.26.14:063][855]LogExit: PendingNetDriver SteamNetDriver_1 shut down

So now I'm completely at a loss. Firewalls are down, ports are forwarded, I've tried nearly everything, to no avail.

I'm open to anything, just please help!
