I had the same Problem, devices are coming back after I deleted them.

As a Workaround I decided to delete my Bridge, in the Alexa app and on the Hub and made a fresh new one wich worked fine for me.

Ok, thanks for the suggestion, I will give it a try.

Do you have any special network setup in place? VLAN, Firewall, etc.

[MichaelVetter1979]

No, there isn't anything special with my network. Home assistant runs on a VM on my NAS. The NAS has a LAN connection. I have two WLANs, one for 2.4 GHz and one for 5 GHz, the Amazon Echo devices are on the 2.4 GHz WiFi. IPv6 is enabled.

Perhaps I should mention, that there are several different Alexa devices in the network (4x Echo Dot, 1x Fire TV Cube, 2x Fire TV Stick, 1x Echo Studio, 4x Alexa Android App). I'm not sure, if that can cause any issues, but alle device management for the Alexa was done with one Android Phone.
