This started recently & it might be an error as I am pretty sure I am not behind proxy.
I am using static IP address.
Yes, it’s because the website is behind Cloudflare and they enforce IPv6 support. If you have a IPv6 enabled on your connection, it will use that ; BUT the forum doesn’t support well IPv6, so I need to enable an option in Cloudflare to use some fake IPv4 and it’s being detected as proxy by the website.
I’m trying to test things, but I can probably removing that warning anyway, doesn’t matter.
