Thanks for your response.
>The same happened to this forum . Was it cloudfair or another company?
It was and still is cloudflare. I can understand them blocking or restricting access for a week or two if the site has been hacked or there's been a DDoS attack. But like I said, it's been much longer than that and I haven't done anything in particular other than attempt to visit the website.
From Cloudflare's website...
"If no suspicious activity is observed from the visitor’s IP address after a two-week period, Cloudflare stops challenging the IP address."
Don't know to what degree cloudflare views activity as suspicious but I generally visit only once or twice a day. You mentioned sabotage but apart from a cloudflare-related post back in June, I haven't come across anyone else having to do the captcha 'challenge' to enter davidicke.com. The vpn I use (Nord) is one of the largest and has plenty of servers (80 in Japan), so it seems a bit odd that cloudflare would treat so many IP addresses as suspicious in one country (Japan) for such a long period, but not in another (the US). I contacted the vpn and they suggested a few things like changing the protocol and DNS servers etc but that didn't work out. The following is info for website owners about configuring cloudflare's IP Access Rules
IP Access Rules allow allowlist, block, and challenge actions for traffic based on the visitor's IP address, country, or AS number.
There are four configurable actions for an IP Access Rule:
(...)
Challenge: Requires the visitor to complete a CAPTCHA before visiting your site. Prevents bots from accessing the site.
I'm not that technically minded but being able to successfully connect directly via the US but not Japan would seem to suggest it's not my computer but more an issue with cloudflare? Not sure whether this is pertinent but perhaps the webmaster at davidicke.com could tweak the IP Access Rules slightly in cloudflare's firewall app to allow easier access from countries like Japan? Would any of the moderators be able to check that?
Thanks
