I'm unable to Pair this device through Matter. I can through GHome and Alexa through Matter but when attempting to add through Home Assistants it fails at the last step. If I add it to another service and try to pair it through say Alexa or GHome to HA, it just fails to add and says try again.

Enabling IPv6 in the router (maybe also enable mDNS) and in Synology DSM helped me.
Now HA network settings will show the IPv6 address and power strip pairing without problem.

Already is, I have multiple devices connected already through Matter. Matter requires IPv6 to work to begin with. I also do not have Synology.
