[SOLVED] Bluetooth: "ioctl_connadd(): Protocol not supported (93)"

Error log when I try to connect in bluetoothctl:

After pairing, the keyboard just starts reconnecting constantly with these errors.
Updating the kernel, re-peering, restarting the bluetooth did not help.

Keyboard model: caseflex bt

Just changed kernel from linux to linux-lts. Now works good
