[Bug] Bad authentication error

[gpopesc]

Describe the bug
bad authentication error

To Reproduce
Steps to reproduce the behavior:

After last Synology update 6.2.4 I had to reinstall your script.
I respect all your steps but I get Authentication failed.

I edit your script with my credentials and my IP and when I run it in command line, I get "badauth"

Additional context
I used your script before with version 6.2.1-6.2.3 and I hadn't any problem

I have got the same problem.
Since the update the /sbin/cloudflareddns.sh have been delete and /etc.defaults/ddns_provider.conf have been restore to default value. So i follow also all the step butt for me the last instruction is not working :

cat >> /etc.defaults/ddns_provider.conf << 'EOF'

        modulepath=/sbin/cloudflareddns.sh
        queryurl=https://www.cloudflare.com
        website=https://www.cloudflare.com
E*

so i try to understand cat and i rewrite enterly the ddns_provider file with this command

cat <<EOF > /etc.defaults/ddns_provider.conf
