[WLAN access rejected: incorrect security]

I am trying to log in Rockauto.com I get this error when I try to log in. I have verified that no security updates exist for the Nighthawk AX6 AX4300.

[WLAN access rejected: incorrect security] from MAC address 34:00:8a:e3:68:96, Thursday, Sep 18, 2025 20:15:19

How can I fix this, to be able to log into Rockauto.com?

Any device on my network will not allow Rockauto.com as well as any browser and even cell phones if they are wireless connected.

Rebooted everything

Flush DNS

I have changed the DNS servers to see if this helped, no change

I know the rockauto security certificate is from Feb 26 2025 and they are using TLS 1.3

and says connection is encrypted and authenticated using AES_256_GCM and uses X25519 as the key exchange mechanism.

Do I need an update of a security certificate? How can I do that with the router?

It seems that the router is not allowing the web page to authenticate?
