MQ Adapter 6.5 intermittent ADA.600.3033 and MQ 2538 through firewall

When a firewall is between WM and MQ, we get these errors several times a day. When reprocessed, works fine. What can I look at? I’m fairly new to WM.

In dev and qual, we removed the FW. This is prod and we cannot remove it. this has been going on over a year. just upgraded prod to WM9.7. Thanks for any input!! Gina

Hi Gina,

what is your Fix Level of MQ Adapter?

What is your MQ Version?
Which version of the API are you running?

Additionally you should try to check the network.
