I can't access the web gui after changing hardware, but all services are working fine

[Fitin]

Hi everyone, I got a better hardware for my pfSense that I had installed on an old 4th gen i3 4160 PC with 4GB RAM, I upgraded it to a 7th gen hardware with a Core i5 with 8GB RAM. In order to not have to reinstall from scratch, knowing how versatile pfSense can be, I simply put the same HDD in the 7th gen hardware, everything started fine, the type loaded as if nothing had happened, it seemed like it had always been on that hardware, I just had to reassign the network interfaces, all the servers connect to the internet and all the rules work, now the only thing I can't access again is the pfSense webgui in any way

Any suggestions other than reinstalling

What does the console menu shows you ?
And :

ifconfig

Double check that you didn't mix WAN and some LAN port.

ps aux | grep 'nginx'

sockstat -4 | grep 'nginx'

The new system has new ? other network interface ?
If they got reordered at start, what previous firewall rules will be assigned to what interface ? ( just thinking out loud here )
