Question Unable to pair bluetooth device again after device has been removed from bt-list on Win11

[yzq11]

Hi,

I've had a pairing issue with my bt-speaker and during troubleshooting i removed the device from the Win11 bt-list. After that i couldnt reconnect the device again.
I reinstalled the driver, restarted the bt-service, replugged the bt-usb-device, deplugged my pc from power and all the other tips i could find on the internet. Nothing helped to reconnect my speaker. My speaker is correctly discovered by Win11 when I press the bluetooth button on my speaker.
After nothing helped, I removed my mobile phone and my ear buds from the Win bt-device-list and faced the same problem like with my bt-speaker. The devices are discovered correctly by Windows while paring mode is active, but none of them can be connect to my pc.

I hope anyone can help me :/

Thank you in advance!

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)?

Disk drive(s): make, model, capacity, how full?

List of all connected peripherals.

Wired or wireless network?
