Can't open site from WiFi on hAP ac

Hi,
Once upon a time … I can’t open site obi.ru! Just can’t open. While connected via WiFi on my laptop. When I’ve switched to a different WiFi on my central router and have no problems. Ping is Ok, lookup is Ok, trace is Ok but just can’t open site. No proxies, no specific settings. Please help what is my exam actions to re solve, I’m aware my Mikrotik became bot … hacked. Thx,

Netinstall your device and configure from the beginning.
