Run IBM-MQ server on Linux using Docker images(icr.io/ibm-messaging/mq:9.3.1.0-r1).

When using go-jms to access IBM-MQ on a win64 machine, error 2539 occurs.
{errorCode=2539, reason=MQRC_CHANNEL_CONFIG_ERROR, linkedErr=MQCONNX: MQCC = MQCC_FAILED [2] MQRC = MQRC_CHANNEL_CONFIG_ERROR [2539]

After searching online, it was found that this error is caused when an MQCONN call is issued from a client to connect to a queue manager but the attempt to establish communication failed. Common causes of this reason code are:
The server and client cannot agree on the channel attributes to use.
There are errors in one or both of the qm.ini or mqclient.ini configuration files.
The server machine does not support the code page used by the client.

However, the user has confirmed that the channel type is SVRCONN and all other configurations are correct. They have also tried setting MQCCSID but the same error still occurs. Additionally, there are no related error logs in the server /var/mqm/qmgrs/***/errors/AMQERR01.LOG file.

Use 9.3.1.0-IBM-MQC-Redist-Win64.zip for Windows SDK.

I am running a similar client program on another Linux machine, which can access and consume messages normally.
