MTA-STS not loading

[Elm4718]

I keep getting the below in my nightly emails, but I’m not finding a way to resolve this issue.

STS policy fetch for domain ‘[domain].com’ failed with error:
STS policy fetch for domain ‘box.[domain].com’ failed with error:

I’m not sure if there is a script I should run or there is something else.
I shouldn’t be missing any DNS records as I’m aware
If I go to mta-sts.[domain].com it loads the Mailinabox page.

My DNS is hosted external since I am hosting other services on the domain, as well.

I wonder if part of it is I don’t have _smtp records, acccording to this thread

[SOLVED] V0.50 MTA-STS policy is missing: STSFetchResult.NONE

A missing MTA-STS policy won’t affect incoming mail compared to the previous version of Mail-in-a-Box but indicates that the new MTA-STS record (which adds security for incoming mail) isn’t present. This might be a normal DNS propagation issue. Or maybe after an upgrade we don’t immediately publish updated DNS records. Can you report back tomorrow if the error is still there?

My admin page does nto generate these records in the External DNS page. I’m not sure what I am missing.
