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"

Unable to join session for steam (Can Create)

Hello everyone! Im wondering why in my project's server browser you cant join a game, the game shows up with the players name, however i cannot join. the main issue i saw on the logs were errors such as: Unknown or unsupported data type from Steam key data 1000003c 14.

Note, that steam overlay works, and hosting the game works aswell (through steam) I also call a destroy session in the main menu blueprint, this was to counteract a different problem which was (Session (Game) already exists, can't join twice) error

I am not able to pinpoint what the error would be!

Create session blueprint: https://gyazo.com/ab68856afdb8808e38a301c6f4350910

I have also uploaded a full gamelog below Any solutions would be greatly appreciated! Thanks

Hey CruelALpha,

I recommend taking a look at the following threads:



This likely comes down to a need to increase your Public Connections when Creating and Joining games, as stated in the other threads.

Also, if you're testing Steam multiplayer in a packaged game, always test on two separate PCs, as there are multiple complications that can arise from attempting to test two instances on the same PC if it is not in-editor.

Have a great day

For everyone using steam having the same problems: The steam servers are region locked. I don't know if it is only for AppID 480 but still worth a try.

If you and your friend are not in the same region it will not connect.

You can change your region by changing your download region in SteamClient>>Steam>>Settings>>Downloads>>DownloadRegion. Make sure your friend and you are using the same servers.
