Auth timeouts after key press

[DPR1604]

Hi folks,

Having a strange issue getting the module setup for ssh.

So in testing I have added the following to pam.d/sshd

auth sufficient pam_yubico.so id=[REDACTED] debug authfile=/etc/yubico

And this to sshd_config

Match User [REDACTED]
AuthenticationMethods keyboard-interactive

also changed ChallengeResponseAuthentication no to ChallengeResponseAuthentication yes

This setup works on other servers only difference config wise is sufficient is required in pam.d/sshd

The behavior originally looked to be DNS related but running a tcpdump on port 53 shows the module performing lookups fine.

Essentially what happens is after the keypress it looking to accept the key but does not log in eventually sshd times the connection out

I'm not sure if it's related but I have spun up a test server with the same network config and that works fine the only difference is the servers with issues have been converted from centOS 8 to alma linux via the alma deploy script.

Nothing shows up in the debug log when attempting to auth via ssh, hoping someone can share some additional troubleshooting steps that might narrow down the problem

Thanks in advance.
