I'm trying to connect to a remote queue manager via host address, but when I try to configure the connection using MQ Explorer, it comes back an error message
Reason 2009 (AMQ4059)
Anyone can help me to understand why MQ Explorer gives me this error?

could not establish a connection to the queue manager - reason 2538. (amq4059) severity: 10 (warning)
explanation: the attempt to connect to the queue manager failed. this could be because the queue manager is incorrectly configured to allow a connection from this system, or the connection has been broken. response: try the operation again. if the error persists, examine the problem determination information to see if any information has been recorded.
Please tell how do I resolve this.
The problem: MQ Explorer on a Windows Server machine with connections to a number of remote queue managers in a Linux env. I have migrated a new queue manager to the Linux env and added it as a remote queue manager in MQExploirer, but it will not connect, returning the following error:
Queue manager not available for connection - reason 2059. (AMQ4043)
Severity: 20 (Error) Explanation: The attempt to connect to the queue
manager failed. This could be because the queue manager is incorrectly
configured to allow a connection from this system, or the connection
has been broken. Response: Ensure that the queue manager is running.
If the queue manager is running on another computer, ensure it is
configured to accept remote connections.
Things I have already checked:
MQ Explorer connects to other remote qmgrs on the same machine
The configuration of the new qmgr connection on MQExplorer is identical to the preexisting ones
The new qmgr is up and running
I have a telnet connection from the windows env to the new qmgr's port
The new qmgr has the same channel and listener with the same configuration as the qmgrs that connect successfully
Most of the advice I've seen on this problem is covered by points 1 and 3. Can anyone suggest anything else I can try?
We've tryed to test connection to the remote queue manager after installing MQ client v7.5 on Windows Server 2019. We've used Rfhutilc for this and got 'Host not available' inspite of the fact that telnet connection to the corresponding address was succecfully established. Also we tryed to connect using MQ client v9.0 with the same result.
AMQERR01.LOG (client v.7.5) reported following details:

AMQ9208: Error on receive from host 'X.X.X.X'.
EXPLANATION: An error occurred receiving data from 'X.X.X.X' over TCP/IP. This may be due to a communications failure.
ACTION: The return code from the TCP/IP recv() call was 10054 (X'2746'). Record these values and tell the systems administrator.

AMQ9202: Remote host 'X.X.X.X' not available, retry later.
EXPLANATION: The attempt to allocate a conversation using TCP/IP to host 'X.X.X.X' was not successful. However the error may be a transitory one and it may be possible to successfully allocate a TCP/IP conversation later.
ACTION: Try the connection again later. If the failure persists, record the error values and contact your systems administrator. The return code from TCP/IP is 10060 (X'274C'). The reason for the failure may be that this host cannot reach the destination host. It may also be possible that the listening program at host 'X.X.X.X' was not running. If this is the case, perform the relevant operations to start the TCP/IP listening program, and try again.
Here is an example of how traffic data looks like when Rfhutilc refuses to connect to the queue.
As soon as according to the picture there was some code page issue we've tryed to set MQCCSID environment variable with the value 1208 and it helpled.
Also connection attempt via Rfhutilc was succeful while running under another user with login "admin" even though without setting MQCCSID variable.
But I failed to find explanation for this. Did the CCSID of the MQ client differ from system code page of what? And how could I find out default CCSID of MQ client then?
MQ client v7.5 worked just fine on the Windows Server 2012 R2 right after installing. Rfhutilc v7.5 was used both on Server 2012 and Server 2019 for testing.
I create a queue manager like QMTEST in IBM WebSphere MQ Explorer. I want to connect to a remote queue manager (remote ip address). I followed these steps:
add remote Queue manager
Queue manager name: QMTEST [Next]
Host Name or ip Address: X.X.X.X(remote ip) [Finish]
But I couldn't connect. I got this error message 'Could not establish connection to the queue manager-reason 2538.(AMQ4059)'. What can I do?
The four digit number in your error message is an MQRC (MQ Reason Code). This number gives you more information about what went wrong. You can look it up in Knowledge Center.
MQRC_HOST_NOT_AVAILABLE (2538)
There is a list of possible things that could cause this error. My guess is it is likely to be the first one, you have not started a listener on the queue manager, since you do not mention doing that in your question details.
You should also read the following link which is some basic details on how to connect to a remote queue manager. You appear to have the MQ Explorer side sorted, but perhaps not the queue manager side.
Setting up the server using the command line
Please ensure the listener is running on the remote queue manager side. The default MQ listener port is 1414. If the listener is running then check the queue manager error logs for any connection errors from the MQ explorer.
Are you sure the qmgr and its listener are running and that you have a SYSTEM.ADMIN.SVRCONN channel? That is the server-connection channel used for remote administration of a queue manager. This technote may be helpful.
Is this on a modern Windows or Linux server? If so, did you open the port (i.e. 1414) in the firewall?
Sometimes when we create a Queue manager remote administration objects are not created that's why we get such errors because it is unable to find these objects. To create them right click on the queue Manager, Select Remote Administration objects and create them and start the listener.
I experienced this same error and the queue was configured correctly.
I was using Eclipse and switched to the MQ Explorer setup available from IBM web page.
After that, I was totally able to see the queues and everything I was supposed to see.
We are have a IBM websphere MQ[v5.2] on AIX platform and my machine is windows 7 pro which has MQ client v7.5.
I tried to connect to server remotely but i received a Authorization error message. This is because my local user account does have rights to connect to queue manager remotely.
So,i created a new user account in my system with some name as on server which has rights to put/get message and now i am able to connect in client mode[Websphere MQ v7.5].
I don't know whether it is actually connecting to server but it is not giving me authorization error message so i took it as success. But the issue is, when I tried to put message into queue from cmd using amqsputc Queue_name mqm the queue is opening and taking a message. But when i tried to get the message using command amqsgetc queue_name mqm it says "NO MORE MESSAGE".
What could be the issue?
Screen shot:
The fact the amqsputc doesnt give an error, and the fact the amqsgetc runs through to success implies the functionality is working. However, it finds nothing on the queue which makes me very suspicious that you have an application listening on that queue, which will consume the message as it arrives and hence before your amqsgetc. Check DISPLAY QSTATUS in runmqsc for IPPROCS on the queue - is it 0 when amqsgetc isnt running?
