Just ran into a strange problem. I do a standard Hotspot installation and follow the instructions for an external login page.
It all works fine the first time I connect. When I disconnect from the Wifi hotspot and connect again the Hotspot does not redirect me to the external page and says it cannot be found.
When I reboot the router it works the first time I connect and then when I disconnect and connect again it does not redirect me and no access to the external login page. Wonder if it's a Firewall problem?
I am using a RB 951UI - 2HND - RouterOS v. 6.33 (stable)
