Failing Security Update

[Galaxy_Girl64]

I've been unable to download a security update on my Samsung S21+ since yesterday. I've made multiple attempts to download the update and it keeps failing. System Update 56, Android Security Patch

Error Code 407

Same for me on S24 Ultra

You may need to have your phones reflashed at service center.
