Hello everyone

I need help; in fact, I can no longer log into my bank on my computer, but I can do it on my mobile by disabling the Wi-Fi.

Thank you in advance for your input

    Hello.

    It would be nice to be more precise.

    You say it's a portable device? Laptop or mobile phone? Disconnecting from WiFi means switching to mobile network or Ethernet.

    If by portable you mean mobile phone, and if by disconnecting from WiFi you mean using the mobile network, that means your box's IP is blacklisted by your bank, and this can also happen if you use a VPN.

      Thank you for your quick response. I can't connect on the desktop computer and on my iPhone, I can't access the bank when I'm on Wi-Fi. When I disconnect Wi-Fi on my mobile, it works. I'm not using a VPN. I hope this will be enough; until yesterday it was working very well, it started this morning around 6 am. I restarted the box just in case, but the problem persists regardless of the browser I use.

      Thank you for your help.

      Since it is only with your box's IP that this is blocked, it is your bank's website that is blocking this IP; check with your internet service provider about this.

      Hello,

      I think the operator, especially SFR, can't do anything about it either. Today, IPv4 address blocks are becoming so rare that operators buy them on the markets and can end up with foreign blocks or blocks that have been used for dubious purposes. As time goes on, the IPv4 addresses sold on the secondary market are getting worse and may end up on blacklists that firewalls from banks or others purchase. It's a whole mess when they find themselves in that situation.

      In parallel to this, SFR uses CGNat, so its IPv4 addresses are shared among quite a few customers (up to 256, I believe). If one of them does something nasty on the internet and gets listed on a blacklist, then without batting an eye, the list sweeps away everyone in that group all at once.

      These lamentable practices are slowly destroying the internet, especially the ancestor of the internet, IPv4.

      It's certain that the operator can't do anything about it, and they won't change the IP address for that reason. The bank will also be taken by surprise because they have no control over the blacklists they buy to do the job for them; they probably don't even know which responsible party is behind the blacklist.

      The simplest solution is to go through a distant NAT (VPN) or via Cloudflare, which maintains a good reputation among professionals. For now, it remains effective and free.

      From time to time, drop SFR, it will be better for you.

      When they start with nonsense like that, it's not looking good.
