Hi Sandro, thank you for your answer but I have of course tried with several browsers, and several devices for several days (and I have cleared the cache several times). It doesn’t seem to be the issue here.
I know there is no such redirect in place as I have deleted it myself… and yet, on several different browsers on different devices, despite clearing the cache, the .biz is still redirected toward the .com.
It doesn’t come from the browser (if it was the case, it wouldn’t happen with a different browser). If it did, I wouldn’t be posting here for help…
Except that there is literally nothing on any server in that case : the DNS is set up toward Cloudflare and that’s it (I set it up myself). Until a few days ago, the page rule was the only thing set up for this domain. Now, it should follow the DNS settings toward the new IP address but it doesn’t.
There must be a bug somewhere on Cloudflare. I just don’t know where.
