time out error in firefox and safari after update macOS 15 to 15.0.1

I recently updated my macOS 15 to 15.0.1. After that, I got some network issues.

when I connected with ethernet at that time, firefox and Safari could not connect with the network, but Google Chrome worked fine, and I could open sites. (Also app store,setting,mail etc got network issue)

Firefox gives a message after a long time: "The connection has timed out" and Safari gives a similar error.

But when I switched ethernet to personal wifi at that time, all network applications worked fine, including Firefox and Safari (Other network required application).
