I flashed HBL branch on Turris Omnia router and passed the guide. Once I did it, then I tried to modify LAN page or even save the default values in reForis and it does not work. It shows: **An unknown API error occurred.** While looking at web developer console it says: > Failed to load resource: the server responded with a status of 400 (Bad Request) Looking more, this is the output which I got from API: ``` {"interface_count":5,"interface_up_count":1,"mode":"managed","mode_managed":{"dhcp":{"clients":[{"active":true,"expires":1626746716,"hostname":"mydevicehostname","ip":"192.168.2.125","mac":"C0:3E:BA:C6:55:76"}],"enabled":true,"ipv6clients":[{"active":false,"duid":"000433147685a43981eb1fd6fa2d1deff1b9","expires":1626746697,"hostname":"mydevicehostname","ipv6":"2001:1488:fffe:6320::83b"},{"active":false,"duid":"000433147685a43981eb1fd6fa2d1deff1b9","expires":1626746697,"hostname":"mydevicehostname","ipv6":"fdca:54d3:47fa::83b"}],"lease_time":12.0,"limit":150,"start":"192.168.2.100"},"netmask":"255.255.255.0","router_ip":"192.168.2.1"},"mode_unmanaged":{"lan_dhcp":{},"lan_static":{"gateway":"192.168.1.1","ip":"192.168.2.1","netmask":"255.255.255.0"},"lan_type":"static"},"qos":{"download":1024,"enabled":false,"upload":1024}} ```
