Is there nobody that can answer? No solutions in any site about EOSplus!

Just why can I not host? I followed this tutorial step by step Using Steam Login for Epic Online Services with Unreal Engine Blueprints - YouTube
But is still says login failed. I only get these two lines in the output log. There is no answer anywhere.

LogOnline: Error: OSS: FOnlineSubsystemEOSPlus::Init() failed to get the platform OSS
LogOnline: Warning: OSS: EOSPlus failed to initialize!

Here is a link to a problem just like yours, maybe it can help?

I have already seen this one. This persons solution was this:

I managed to find what I think the problem could be, in player state the unique ID was being set to nullptr due to the game mode thinking that the player was an inactive player when the PostLogin function called FindInactivePlayer when I launched the test project.

Because I was always staying within the same map while doing the testing the unique ID never got updated after successful login as this PostLogin function had already been called.

So a work around I did was to send the player to another level after successful login, now when the PostLogin function is called the logged in player is not considered an inactive one and the unique ID was set properly and I am now able to create/find/join sessions without getting the cannot map local player to unique id error.

I have no idea what he/she means though.

Hello! From link with eosplus settings, it is my personal account.

So mb i can help you here.

You right, my problem was in unique ID that player have to for create or join session.

You have problem with OSS init. It seems like a mistake in .ini files.

Check out my settings in link Epic Online Services (EOS) Developer Support
