Website downloaded from hosting has problem with ciphers

Hello,

I have downloaded a website which is running fine on server but I cannot make it run on localhost.

The log return:

I have run : php artisan key:generate and config clear, but none seems to help it, it just return all the time this message.

Thank you.

I found out eventually, I expected the key to be set up automatically. However, it expected me to do it manually.

So I just copied the generated string to the .env APP_KEY = STRING; Cleared the cache and that was it.
