Have a delay problem

General

After we successfully connected DS in China, there will be a delay of 2-3 seconds in sending RPC messages, is there any solution? Thank you very much!

This delay problem occurred when we updated to AMS

Hi @user13,

We’ll investigate this further and need more information to determine the root cause.

  1. Has this issue occurred before, or did it suddenly start happening now?
  2. Can you share the session ID where this issue occurred?

Hi @user13,

FYI, we currently do not have a China’s AMS region. Additionally, we identified a few issues with your integration:

  1. Latency Issue: When creating a match ticket, you did not supply the latency, causing your game to connect to us-east-2. We recommend calling QosManager.GetAllServerLatencies to gather latencies and include them in the match ticket to get the best region for your current location. Here is the guide: Unity Integrating Matchmaking.
  2. DS Log Error: We found this error in your DS Log related to RPC. This could be causing the delayed RPC call:

Please address these issues first and let us know if they resolve your problems.

Thank you for your help, when I call GetAllServerLatencies it returns error messages:
{“Error”:{“Code”:“ServiceUnavailable”,“Message”:“The server is currently unable to handle the request due to a temporary overloading or maintenance of the server.”,“messageVariables”:null,“InnerError”:null},“Value”:null,“IsError”:true}

@Damar Please help me. Thank you!

Here’s how I call it

@Damar I also have a problem with GetAllServerLatenies, which takes me about 8 seconds to get a message after I call it

Hi @user13,

Please ensure that the Use AMS QoS Server Url is set to true:

config
config720Ă—260 23.7 KB

Additionally, if you are using a VPN, it may interfere with the UDP protocol in some cases. Other customers have reported this issue and are experiencing similar problems.

@Damar Ok thanks, I got a new question:
{“Error”:{“Code”:“NotFound”,“Message”:“The server has not found anything matching the Request-URI.”,“messageVariables”:null,“InnerError”:null},“Value”:null,“IsError”:true}

Hi @user13,

It is difficult to determine the problem without a log file. Can you share the text log file in our private message? Here is a guide on Unity - Manual: Log files.

If you are uncomfortable sharing the log file, you can filter out all the AccelByte logs and share those instead.

Thank you.

Thank you, after looking at the logs, it seems the function GetAllServerLatencies was outdated and needs a fix. Meanwhile, please try to use GetServerLatencies, it should be working.

@Damar Ok, thanks, but I get another error after calling GetServerLatencies:

Hi @user13,

Apologies for the late reply. The QosManager error will be fixed soon on the next SDK version release.

Thank you.

Hi @user13 , we have released new SDK version to fix the QoS Manager error. Please find the version below :
https://github.com/AccelByte/accelbyte-unity-sdk/releases/tag/16.23.1

Release Notes :

Added a validation check to ensure that server addresses returned by QoS are valid before resolving. If a server address is in IP format, it will be used directly.

Please let us know if you still experiencing any issues.
Thank You

Okay, it’s working. Thank you very much!!
