Connecting to HomePod after wifi router change

I recently upgraded my home wifi routers to a LInksys 6E mesh system. All my Apple products connected well except Homepod. it keeps saying " I am having trouble connecting to the internet" It is not being recognized in my phone -16pro. Worked fine before the router switch (also a LInksys mesh router). Is there a way to reset it or some other way to connect? Any help will be greatly appreciated. thanks
