I have docker running on a Raspberry Pi2 and I use it to control my home automation.
For a couple a week, I cannot access to Node-Red because the login fails due to wrong password (I'm quite sure that the passowrd is correct). And also the login takes some time before show wrong password message.
I tried to modify the password editing the settings.js file but the file is read-only.
So I tried to change the permission to the file with chmod but this is the output:
chmod: changing permissions of 'settings.js': Read-only file system
What can I do too access again to my flows?
Thanks in advance for the help.
