I've been using StatusCake.com since a few years for reporting downtimes to me, without much problems. Only sometimes they report something as down, but there is no issue when I try myself; this has probably more to do with me using a free tier so they don't retest soon after a failure.
However, since 16+hours now all my Opalstack websites are reported as 403 and continue to be so; in reality absolutely no problem. The incident report states that server doesn't seem down, just rather actively refusing request:
<<The monitored URL returned HTTP 403. The server understood the request but denied access. This often points to WAF, CDN, bot protection, authentication, IP allowlisting, or permission rules. >>
However, I'm not using any CDN or auth, listing or permission rules. I've not changed any settings for firewall or robots.txt. Any obvious cause I'm overlooking? Or others with same experience?
Thanks!
