For what it’s worth, the reason you’re having this problem is almost certainly related to the suddenly stratospheric level of scraping activity being conducted by AI bots.
The AI companies are vacuuming up everything on the internet to train their language models. The amount of traffic is incredible, and has become destabilizing and sometimes incapacitating for smaller websites with limited bandwidth. The scrapers are supposed to respect the website’s configuration if it tells the bots not to scrape, but the AI companies are already operating in an ethical gray area and many of them disregard the configuration and scrape anyway. To defend themselves, many websites have turned to Cloudflare to try to block the bots from entering.
Here’s a background article if anyone wants more information.
It’s possible that you’re originating from an IP zone that has significant bot traffic, and as a result Cloudflare is raising a stiffer defense for you. It could also have something to do with your browser configuration that’s tripping their automated alarms. It’s impossible to say, really.
This doesn’t help you solve your problem, but it does provide some sense of why it’s happening.
And if the AI scrapers aren’t reined in, then the problem is going to get a whole lot worse, for all of us, before it starts getting better.
