Can't find IP address

I tried to modify the static IP address of the Raspberry Pi. After the modification, I can still use it and find the IP address. However, after a week, I can no longer find the IP address and cannot log in with SSH. My two The modules are all like this: RevPi Core3 and RevPi Connect+, is there a way to solve them.
Steps to modify static IP address：
1、Input command：sudo nano /etc/dhcpcd.conf
2、Add content in dhcpcd.conf：
interface eth0
static ip_address=192.168.1.100/24
static routers=192.168.1.1
static domain_name_servers=192.168.1.1

Hello with interest I read your description of the problem.
I can understand the steps you have taken.
Probably you just forgot one letter
Shouldn't it say "interface eth0"?

Hello，
I know that resetting the system can solve the problem, but my project must have a static IP address. The same setting still causes me to find the IP address. I have tried to reset the system, but if I set a static IP address, I still cannot find the IP address.Do you know any other way, thanks you.

Hi Purecade,
which image version do you run (cat /etc/revpi/image-release)? Is there any error message in the logs after the connection is lost (reboot and check with jourctl -u dhcpcd)?

Hi Nicolai,
I run buster imager.I want to connect my RevPi Core 3,but I can't do SSH login.And my Mirco USB port is broken and I cannot reset the system.For my RecvPi Connect, I fixed the Ethernet port A, but I can't find the IP address for both interfaces. I am very troubled.

Does the local login via an attached HDMI monitor work?

What do you mean with "fixed the Ethernet port"? What did you try to configure the ip addresses (please share complete configuration file)?
