This was due to a silly mistake I made and I got it working. My firewall and crednetials were working fine. However, during the troubleshooting I must have set the SNMP credential to apply to a specific MID Server. It was giving this error when the Discovery was routing via  a different MID Server.

Error: SNMP probe timed out. Target is either unreachable or there are no valid credentials for it.

Solution:
For my situation, I updated the specific credential record (SNMP V3 credential) so that it can be applied to "All MID servers". 

I hope this helps.

Regards,
Jude.
