Hi,

I assume f8Jqvw8bLL6nc6H is not your password, right?
Inside your docker directory, can you please run the following command and post the output:

grep -r f8Jqvw8bLL6nc6H .

If the result contains sensitive information, please replace all sensitive letters with an x but leave all the other characters (spaces, quotation marks, etc.) intact which is necessary for troubleshooting.
