awk to process multiple lines and return several strings

I have these strings:

I'm used to using sed, but I know it will only process line by line.

I've been trying to use awk for a while, but since I'm not familiar with it, I'm still struggling. But, I'm also open to other suggestions.

I just want to look for the keyword INVALID: EXPIRED and then return the domain name at the next line, and finally, it should have this output:

www.domain2
domain6.com
domain7.com
