The client was on a cell phone on the cellular network for internet.
As a sanity check, I backed up my configuration and reinstalled opnsense to see if the problem persisted. It did not, the reinstall fixed it. I have not had a chance to compare configurations to see what change was made that caused the issue, but it has been resolved. Thank you for your help!
