Issues with advanced sessions steam join and player count

This have been a pain for my head for a month. I have two issues with advanced sessions using steam. First is that found session always shows 0 players in game even if that’s not true. Ok that’s a problem but not fatal. But second one is really bad. For some reason my players can connect to dedicated server using sessions with no problems, but when I try to host session for listen server from client(create session, open level with listen option), it succsessfuly shows in server browser but connect fails for some reason. I am using two different steam accounts on two different machines for test. I’m dealing with this issues on all configuration builds both Client and Default changing this option doesn’t help. All sessions stuff Host/Join is in my game instance class(AdvancedFriendsGameInstance as parent), perfectly fine works with dedicated server. Unreal version is source build 5.2, only plugin I am using is advanced sessions steam. Any suggestions on how to resolve these will be good. Thanks for any help

Same issue here. After like 2 days of browsing forums I heard that this is a bug with 5.2, and instead, we should use 5.3. (There is another method but you’d have to completely rebuild unreal again, so I never looked into that one.)

As for the first , I have exactly the same issue. I use source build of engine, v5.3.0-release with Advanced Sessions Plugin (5.3). The session is shown in the Steam Server Browser, but the number of players is always zero. Tested for all build configurations, both client and server. This is not a serious problem for me, but at the server setup stage it misled me.
