Error while sending: net::ERR_ACCESS_DENIED (-10)

[ZweiundzwanzigSiebtel]

It seems like this message pops up for every request (Ping, Discover, GET, ....).
I tried it on the eclipse coap site, coap.me and a localhost coap server

Is there somewhere a parameter value, that I have to change?

I tried the extension and I could only observe an "ERR_ADDRESS_UNREACHABLE" when trying coap://localhost/ (no idea why, did not look further).

Using coap://127.0.0.1/ or coap://coap.me/ worked for me without any messages popping up.
