This is particularly useful if you want to do the commits manually using the git cli or another workflow. One of the important thing to note is that the workflow will still do the keepalive commits, if you want to disable it you can use the `enable_keepalive` option instead.	No

FAQs and Common issues

Error Code 128
Looks like your website returned *XXX*, There is nothing blog post workflow can do to fix it. Please check your website's RSS feed generation source code. Also double check the URL.: This will happen if your website is blocking requests from the GitHUb IP addresses. It can also happen if you give the workflow an invalid URL. First, check your URL. If it's working fine on your computer, then try debugging it using https://github.com/marketplace/actions/debugging-with-tmate establish an ssh connection with the Github runner and try to curl -I <URL> This will give you a 200 status code if your website is responding correctly. If its not responding with 200, you need to check your website's feed generation source code, you can also contact your hosting provider/DNS provider to know if they are blocking the GitHub public IP address. Some companies do that to prevent spam and DDOS attacks. As the message says there is nothing I can do to fix this issue, it needs to be sorted out with your hosting provider.
