question

1. Have you checked our Mirror sample here? MpsSamples/UnityMirror at main PlayFab/MpsSamples (github.com)

2. Have you used LocalMultiplayerAgent to make sure your game server integration with our Game Server SDK works? PlayFab/MpsAgent: Azure PlayFab Multiplayer Servers LocalMultiplayerAgent project and helper libraries (github.com)

Hello,

1. Yes, I was doing my project somewhat similar to provided Mirror Sample. However, I noticed that server uses telepathy transport, while I'm using KCP transport. I don't believe that this is the issue...

2. Yes I have tested with LocalMultiplayerAgent and I get the same results as from the dedicated server, that I uploaded into Playfab.

To be more clear, I will list the steps that I tested my game and why I find it strange.

1. I opened 3 tabs, 2 of them are built into the Windows platform and 1 is built into a dedicated server. Then, I connected clients with the server and everything works as intended, with 0 errors.

2. I tested with LocalMultiplayerAgent, I created a Linux container and it seems that when I connect my clients and start my game, the server is having problems sending information to clients, however, it does not produce any errors.

3. I tested by uploading my server into Playfab and using matchmaking I connected my clients, I still have the same problems as in 2.

Lastly, when inspecting logs produced by Playfabs I noticed 1 strange error, that I believe is not produced by my server.

{"log":"Curl error 35: Cert handshake failed. verify result: UNITYTLS_X509VERIFY_FATAL_ERROR. error state: 7\n","stream":"stdout","time":"2022-05-31T10:42:49.533967088Z"}

{"log":"Curl error 35: Cert handshake failed. verify result: UNITYTLS_X509VERIFY_FATAL_ERROR. error state: 7\n","stream":"stdout","time":"2022-05-31T10:42:49.534983807Z"}

{"log":"Unable to complete SSL connection\n","stream":"stdout","time":"2022-05-31T10:42:49.561478487Z"} {"log":"Unable to complete SSL connection\n","stream":"stdout","time":"2022-05-31T10:42:49.561612789Z"}

Finally, I'm attaching the console log if further inspection is needed.

Sincerely,

Thanks for posting the logs. First of all, the server transitions to the Active state so the lifecycle flow looks great, from a PlayFab game server perspective. However, the server seems to exit (crash?) right after the UNITYTLS_X509VERIFY_FATAL_ERROR error.

I don't think that the UNITYTLS_X509VERIFY_FATAL_ERROR is caused by any code we have in the Game Server SDK. Are you trying to connect to any external HTTPS services? If you are using a Linux container, sometimes they don't have the necessary certificates installed. Can you try updating your certificates in your Dockerfile? Something like this might do the trick

Dockerfile is the issue u need to instal certificates when building. Dockerfile should look like this:

FROM ubuntu:20.04

WORKDIR /game

ADD . .

RUN apt update

RUN apt install -y --reinstall ca-certificates

EXPOSE 7777/udp

CMD ["/game/Game.exe"]
