Firewall not picking up IP for FQDN

Question

have a firewall rule to allow outgoing connects for teamviewer using a FQDN of *.teamviewer.com 
 
 However, when local endpoints trying to connect using one of the IPs in this FQDN the firewall blocks the request due to it bypassing the rule. 
 
 I can see the IP under this FQDN in the hosts and services. 
 
 This rule has been working fine for 12+ months. Any idea why this may not be working now?

Hello, 
 Greetings, 
 You may enable the FQDN-host eviction with the 60 seconds of the interval and validate it further. 
 You may also refer to the below KBA:

 If enabling suggested settings does not help, I would suggest raising it to the support as we have one known issue (NC-100716) with it.
