Windows Agent Failing Randomly

Troubleshooting

1

CMK version: 2.2.0p32.cce
OS version: Appliance 1.7.4

One of our Windows servers seems to stop talking to CheckMK, a service restart restores communication but it will randomly fail again in the future. From looking at the logs I can see the following which I think is the issue. Any suggestions on how to fix this or what is making it break?

I’ve actually been experiencing the same thing. We’re running cloud version 2.3.0p22.

Noticing the same with Windows servers.

Did you get any resolution. I did open a ticket with support as well.

Piling on with the same issue here, intermittently across all our Windows servers. @BTNE what did their support day - were they able to resolve your issue?
