RouterOS 6.17 - Disabled Radius Login

MKT Access reverts to default UN and PW

If there is already an entry for this bug I apologize. I have been searching through the forums for sometime and I have been unsuccessful.

The setting I am referring to is located in System>Users>and AAA is disabled frequently. Allowing access with the default username and password.

The issue I am experiencing only seems to happen when the following conditions are met.
Hardware: Cloud Core
Router OS: MikroTik RouterOS 6.17
OSPF Enabled

I can re-enable AAA and it will begin to work for a while. Then in time it reverts back.

Any suggestions? Am I the only one experiencing this issue with the Cloud Cores?

So far we have tried rebuilding the config from scratch as we had a hunch that importing the config between versions is what caused the issue. However after a few days the same problem occurred.

The issue still seems to be isolated to Cloud Core hardware. Any suggestions would be greatly appreciated.

I had this problem before.

NetInstall the device, that fixed it for me.
