Unable to login pfsense verioin 2.7.0

Hi pfsense installed on a HP620 computer will load to login page. It has been running for over 10 months without any problem until recently the switch does no receive a internet connection from the bridge/modem. I rebooted I can see all the logs and the original config is the same except for the wan which is a different ip address. I am a newbie , any advice would be appreciated as i don’t know if it is pfsense or faulty switch. Any advis ewoul db appreciated.

Can you ping the LAN ip on the pfsense?

Tom thanks for your reply I rebooted all my devices on my system by this time internet came back on.
