Cannot refresh/release WAN IP - requires reboot

[axsdenied]

Before you beat me up on this topic being brought up before, in various forms; you're right.  However, in my searching, I found ZERO resolutions outside of "rebooting" which is not what I'd want to do with an enterprise class option like OPNsense.

Internet Provider Context:

• WAN - Cox Cable - Cable Modem (Private/bogon networks blocked and Reject leases from 192.168.100.1 set
• WAN2 - T-Mobile Home Internet

PROBLEM: After an outage or issue with the Cox Cable connection (WAN), OPNsense fails over to T-mobile (WAN2) pretty gracefully.
After diagnosing the issue with the primary WAN connection and bring it back up, I'm unable to get a valid IP from the Cox Cable modem.

ATTEMPTED STEPS TO RESOVLE: If I go to INTERFACES: OVERVIEW, and select the WAN interface (wan, igb0) I do see both "Reload" and "Release" as options for DHCP.

If I attempt either, usually one of 2 things happens:

• I can see the gateway assigned to the interface but i'm given no IP address or DNS servers
  
• It hangs and is completely blank

I can do try these options for many times and the result is always the same.

The ONLY thing that allows me to receive an IP again is rebooting OPNsense.  This tells me, given its inability to communicate properly to obtain a refreshed IP without rebooting is clearly an OS/Driver/OPNsense issue.

Anyone know why this could be?
