Login warning in log although I can login?

Good Morning:
I’m now running NC24 although this issue precedes the upgrade. The issue is I’m getting warnings in the log about login but, as a user, I’m able to login. the warnings are:

Warning core Login failed: ‘kc’ (Remote IP: ‘192.168.200.204’) an hour ago
Warning core Trusted domain error. 192.168.200.204 tried to access using xxx.xxx.xxx.xxx as host. 2 hours ago

I checked the config file and I do have .204 as a trusted domain. The 204 machine is an Nginx reverse proxy. As for the .xxx IP, it’s the IP assigned by my isp and subject to change.

As I’m able to login one could argue that it’s still working. I just don’t like seeing warnings in the log. So the question is how do I correct it?
Thanks for the help
