Failed to save thread network credential

@wmaker I’ve seen that you have helped a few of us with this annoying problem. Could you possibly give me a hand with my system, as it refuses to send the thread key to my iphone?

I’ve posted the relevant details here, but back to your last message in this conversation, I must say I’m actually seeing matterc_udp messages when I run DNS-SD Browser on my iphone.

In my home there are several Apple devices that speak Apple’s implementation of Thread, so that may be a problem.

I do see the small key on my HA instance already, so I should be on a good position to send the key to my iPhone, but that does not seem to work at all.

Any pointers would be most appreciated!

thanks a lot!!
