Peer name changed on its own

My Yacy instance just switched names. It also no longer receives DHT chunks ever since the name changed. I didn’t change any settings. Do names rotate automatically or something?

This happened to me when the settings file were broken due to overflowing the disk.
I set the desired name through the “Use Case & Account” menu.
After that, the name did not change spontaneously.

Perhaps you also have damaged settings file. Check the correctness of other settings, including DHT settings.
