Why your certificates should not expire on a friday

Imagine that one of your certificates is about to expire, and the new certificate doesn’t work. It’s friday and your entire setup is based on containers with mTLS - PANIC! How do you debug the traffic when you are not terminating it in a classic firewall setup? Why can’t you just use tcpdump?
