Now R2 public bucket domain url Unable to connect

I’m currently using r2 and it’s set up as a public bucket.
However, since a few days ago, the public domain is not accessible at all. Note that I haven’t changed any settings at all. This is Korea and I don’t know what the problem is. Please check.

error : DNS_PROBE_FINISHED_NXDOMAIN

domain : https://pub-7401b8eb5e3f4f7397630964b7e0cc21.r2.dev

There have been reports of some South Korean ISPs blocking the r2.dev domain, probably related. It is accessible to me.
r2.dev should not be used for production use either way, it has rate limits on it. It is recommended to use a Custom Domain, which shouldn’t be blocked.
