# Appendix B  - Adding Exception for Default Browser for N2W

### For Chrome

When you first navigate to your N2W instance, you'll see a screen like this. It's nothing to worry about. We are SSL secured but because it is a self-signed certificate, you may want to add an exception to your browser following these steps.
