I see you've powered up 4 days ago and such, it should be the same key.

That is ture @kevinwong but yesterday my computer crashed .. I lost all login details .. luckly i was able to recover my private key ... but before that several times I enter wrong password on login, don't that make this error...

The only problem i can think right now if you're actually manually keying in your password on the keyboard is the capslock function being accidentally activated..

Missing active authory means you are using the posting key, you need active key to power up

True I am sure i am not using posting key @snowflake ... I am using private key , which is same process I have done before !!
