Hi, I’m having this issue with RouterOS v7.1 … Hotspot captive portal is showing a 404 not found error after a few hours of uptime. I fix it through rebooting but after a few hours, the captive portal won’t work again and will show a 404 not found error. See attachment. If you have any input please do share. Thank you.

+1 i have the same problem, couldnt fix it.
Plus, after successfully signing in, status and logout page becomes unreachable.
What device ?
Did you have the same problem on ROS6 versions ?
This is real bug. I have the same problem. I downgrade to v6 in order to use hotspot.
