Authentication error on /updater after update, what is the "secret" code?

Hi to all,
I hope you are well?

I running a Apache server on a hoster.
I don’t use any terminal/shell or openssl.

I have installed normally nexcloud on my Apache server with mysql.
This work very well, but for now after a automatic update it doesn’t work anymore.

I got a error with:


To login you need to provide the unhashed value of “updater.secret” in your config file.

If you don’t know that value, you can access this updater directly via the Nextcloud admin screen or generate your own secret:

php -r '$password = trim(shell_exec("openssl rand -base64 48"));if(strlen($password) === 64) {$hash = password_hash($password, PASSWORD_DEFAULT) . "\n"; echo "Insert as \"updater.secret\": ".$hash; echo "The plaintext value is: ".$password."\n";}else{echo "Could not execute OpenSSL.\n";};'

I really don’t know what have to do.
The last 2 updates doesn’t work either.

But I reinstalled the whole nextcloud.
But for now I don’t have moods to doing reinstall again.

Why every time the update doesn’t work, is it nexcloud unstable?
Do I reinstall the whole nextcloud again.

I hope you can help me.
What for information you need to help me.
Thank you in advance for your help.
Kind Regards,
