I had setup everything before a year and returned back after my vacation. seems the SSL certs were expired and I had genereted new keystores and replaced the bundle in the location.put the new jks file and pwd files in the location and tried to connect to the server using MQ EXPLORER.
I get the below error:
"Could not establish a connection to the queue manager - reason 2538. (AMQ4059)
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.
"
NO errors in the qmanager logs which means it snot hitting the server.
what could it be?
ALso from the same machine I connect using mqmon which throws the error
" Error connecting via client to 'XXXXXXX' RC(2538) Host Not Available."
It works for my other collegues. what should be my problem or what am I missing here?

Did you do a refresh security type (SSL) on the qmgr?

I had only updated my personal ssl certificate used to connect from MQ explorer that was expired and not the qmgr certificate.
DO I stil need to refresh ssl on the qmgr? |

mqmon errror logs says
"AMQ9202E: Remote host not available, retry later.
EXPLANATION:
The attempt to allocate a conversation using TCP/IP to host 'Xxxxx(IP) ' for channel ABC.XYZ was not successful. However the
error may be a transitory one and it may be possible to successfully allocate a
TCP/IP conversation later.
In some cases the remote host cannot be determined and so is shown as '????'.
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
10061 (X'274D'). 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 'XXXxxx' was not running. If this is the
case, perform the relevant operations to start the TCP/IP listening program,
and try again. |

SSL is not mentioned in the errors. Check the listener is running. Check that you have network connectivity to the host and port number. eg. Temporarily disable SSL on the SVRCONN channel (set SSLCIPH to blank) and try to connect using the amqscnxc sample program.

This reason code from TCP/IP means "No connection could be made because the target machine actively refused it". Have you checked that the firewall isn't bouncing you? If you haven't made a connection to this machine in over a year, it is possible that any firewall rules that were added to allow you access have been removed.
Can you ping the machine?
Cheers,
