ARC - double NAT on Google Wifi - Bridge mode enabled on modem

Hi there

I use Google Wifi with three wifi pucks. The modem is in bridge mode.

But I get this double NAT error:

{

“connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},

“external_ip”: {“actual_external_ip”:“87.52.109.46”,“router_external_ip”:“100.101.165.237”},

“status”: “status”: MultipleNatFound

“natpmp_autoconfig”: {“status”:“NotFound”},

“upnp_autoconfig”: {“server_ip”:“192.168.86.1”,“found_upnp”:true}

Anyone know how to fix this?
