I have several Tapo bulbs, sockets and Google mini Assistant. Those has been working well with Google assistant, but this morning when I said "hey google, good morning" it can't find the devices no more, I only heard my Google assistant to say "unable to connect Tapo".

I un-linked and tried to reconnect  account with my Google assistant account, but only what i got was an error message that says "Could not reach Tapo. Please try again."

All devices are connected in the same home Wi-Fi network. Might there be some services down or what might be the issue? Please assist?
