HA could not be disabled

Want to disable HA on a 19.0.1 A/P Cluster and rebuild it. Not even the very first sep to disable HA is working smoothly.

Can't believe this has never been asked - 0 search hits here and on google..

Where can I find helpful logs?

live log says: all fine.I even had a short network interruption*.

Still HA was shown as configured as can be seen above.

Then after minutes, I reload the HA page and it is no longer HA.

but 'I cannot login HA peer anymore via SSH
