| 9506 | The call exceeds the frequency limit. You can initiate up to 5 requests per second. |
| 9507 | The network request queue exceeds the maximum number of concurrent requests allowed. You can initiate up to 1,000 requests at a time. For example, if you keep sending messages when the network is abnormal, the number of messages in the network request queue will keep growing and soon reach the maximum. |
| 9508 | The network is disconnected, no connection has been set up, or no network is detected when setting up a socket connection. |
| 9509 | A network connection has been established, but is created repeatedly due to an internal error. |
| 9510 | Network connection setup timed out. Try again after the network recovers. |
| 9511 | The network connection setup has been rejected by the server due to frequent connection requests. |
| 9512 | No available route to the network. Try again after the network recovers. |
| 9513 | Insufficient buffer capacity for calls. The system is too busy due to an internal error. |
| 9514 | The opposite end has reset the connection, possibly because the server is overloaded. The SDK automatically initiates reconnection. Try again after the network is reconnected and the callback function onConnSucc on iOS or onConnected on Android is called successfully. |
| 9515 | Invalid socket due to an internal error. |
| 9516 | Failed to parse the IP address due to an internal error. The local imsdk_config file may be corrupted and can cause the system to read an invalid IP address. |

Try again after the network is reconnected and the callback function onConnSucc on iOS or onConnected on Android is called successfully. |
| 9518 | The request packet timed out when waiting to enter the sending queue. This error occurs when the network connection setup is slow or the network is frequently disconnected and reconnected. Check whether the network connection is normal. |
| 9519 | The request packet has entered the IM SDK sending queue but timed out when waiting to enter the network layer of the operating system. This is possibly due to the restriction or failure of the local network or a failed connection between the local network and the IM SDK backend. We recommend that you run the IM SDK in a different network environment to check whether the problem is caused by the current network environment. |
| 9520 | The request packet has entered the network layer of the operating system from the IM SDK sending queue but timed out when waiting for the server to return packets. This is possibly due to the restriction or failure of the local network or failed connection between the local network and the IM SDK backend. We recommend that you run the IM SDK in a different network environment to check whether the problem is caused by the current network environment. |

You can log in to the IM console to change the message delivery status displayed in this scenario. For specific steps, see Blocklist check. |
| 20008 | The SDKAppID of the sender does not match the SDKAppID of the recipient, because the SDKAppID is switched on the client but the data is not cleared in the database. To rectify this problem, clear the original database after switching the SDKAppID. |
