I'm running an Axelar node and trying to setup a new one (testnet) on a new server and I just hit the error:

panic: runtime error: invalid memory address or nil pointer dereference

It's actually a pretty simple problem to fix. Then network has undergone an update from 1.0.x to 1.1.x, so for the network to resume you need to make sure you are using the 1.1 version of the axelard binaries.

This is a very common error.
