OpenWrt - No DHCP works well, but can't access main router IP from PC

Clash Royale CLAN TAG#URR8PPPOpenWrt - No DHCP works well, but can't access main router IP from PC
I have a main router connected to internet and then an OpenWrt router as a wifi client of it, with a pc connected via ethernet.

I have set up LAN like this:
Static IP, main router as gateway and dns

Disabled dhcp

And bridged to the wireless client

So the PC gets an IP from the main router and internet works, but I can't access the main router IP through browser or ping from this PC.
What am I doing wrong?
