Hi @Schneider I think looking the error that the RC (reason code) is 2.
Here you can see anothers: https://www.ibm.com/support/knowledgecenter/en/SSFKSJ_7.5.0/com.ibm.mq.tro.doc/q039390_.htm
I think looking the first log you are using always the same client ID? It’s casarfbridge ? It’s banheirosuite ?
My suggestion is to add a random number after this client ID in order to always have a new Client ID when you need to reconnect.
Maybe more things inside this problem 
but I think it’s good to start doing this.
Hope this help you.
