Nabucasa invalid certificate found


I finished the nabucasa trial, canceled and then I subscribed but now I don’t get the URL.
The errors I get:

Can't revoke certificate: urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Certificate is expired
Unexpected error

Anyone experiencing the same issue? what can I do now?

Did you try logging out and back in at Configuration > Home Assistant Cloud?

trying now. I get the same error

maybe I have to remove any existing local certificate? but I don’t know where is stored. will it generate another certificate again?

Should happen automatically I’d imagine. Maybe try restarting Home Assistant, and if that doesn’t work, contact Nabu Casa support.

I tried that also. how do I contact nabu casa support?

I also noticed that I click on “certificate get info” in Configuration->Home assistant cloud I get this:

Certificate expiration date November 18, 2019, 10:27 PM
(Will be automatically renewed)

Certificate fingerprint: ******************

Certificates are stored in your config directory in the hidden .cloud directory. Try signing out of cloud, deleting that folder and restarting HA. Sign back in and you should have new files generated. This takes a minute so be patient. Don’t repeat this process several times because you can hit a rate limit from LetsEncrypt.

Just curious: Did you maybe restore an older .cloud folder from a previous snapshot?


yes. I might have done that by mistake.

this fix worked. thank you

Good to know!

This fix also worked for me thank you for this contribution
