Lose Internet Unless I Select Auto-detect gateway and then back to static

[efrtls]

As it says in the title, after I reboot, the internet won't connect unless I select auto-detect for the gateway, and then back to to the static gateway that I have set up.

Tried searching, however didn't seem to find any topics that matched this exactly.

I'm not exactly new to opnsense, but this behaviour is quite weird.  Any ideas would be appreciated.
