Bug Relay sometimes does not exist on unstable internet

I am having trouble with the relay service and how unstable it is. I am not using the lobby service. I have used the documentation provided by unity but it is still unstable and I'm unable to figure out what is going wrong. I can create the relay, this works every time and I get a relay code back. The result of the relayServerData.Result returns true. I call StartHost() that also returns true. I subscribe to OnServerStarted from (NetworkManager.Singleton.OnServerStarted) which is also called. Everything seems to work, but when clients tries to join, the relay does not exist. This makes no sense to me because there are no errors and everything check returned as it should. I need some way of knowing if it failed... I'm using the relay for mobile, and one thing I noticed is that the error only happens on semi-bad internet. Using my computer with ethernet never produce this error.

 

What Relay, Netcode for GameObject and Unity version are you using?

 

Relay: 1.0.5, Netcode for GameObject: 1.1.0, unity version: 2021.3.15f1

 

You can update Netcode and Unity to the latest version.
Unity : 2021.3.25f1
Netcode : 1.4.0

If this issue still exists, can you share the code?

 

Yes, ill get back to you

 

netcode: 1.4.0 does not exists? the latest version is 1.2.0?

 

You should add package manually to Package Manager.
Add package by name:
Name: com.unity.netcode.gameobjects
version : 1.4.0


https://docs.unity3d.com/Packages/com.unity.netcode.gameobjects@1.4/changelog/CHANGELOG.html

 

Okay it is installed, but im getting the same error.. however, I get this warning now: [Netcode] Runtime Network Prefabs was not empty at initialization time. Network Prefab registrations made before initialization will be replaced by NetworkPrefabsList.

 

This is my code:
Host:


Client:



The problem is that the host is starting, but then sometimes the client cannot join getting an error 404. The host is no throwing any errors and is writing "synching to clients" in the console

 

Can you send relayServerData to NetworkManager like this: UGSNetworkManager.Singleton.StartHost(relayServerData);
And disable ...SetRelayServerData line.

In my opinion, relay server is closing after TTL time.

 

Nothing with that name

 

The host is syncing which means the server should not have closed no?

 

Sorry, Not "UGSNetworkManager",
Correct one : "NetworkManager."

Lifesycle: https://docs.unity.com/relay/en/manual/relay-servers

 

It is not a valid function

It may be a problem with the connection ttl but shouldn't return a callback saying it failed or died then

 

Sorry my bad.
Your script is correct.
Do you get "[Netcode] Syncing Time To Clients" log on editor debug. When you start the Host?

 

yes, every time... and I can connect with the clients some times.

 

There is no indication that nothing is wrong. Only that the clients sometimes cannot join and the relay cannot be found even tho the host is still syncing

 

How about your relay dashboard? Did you configured relay on Dashboard?

 

yes, it is working, only some times is does not

 

Client connecting

client failing to connect:

 

The app is always open, so it is not running in the background. THe transport is as follows:
