Relevant:

- [https://github.com/roots/trellis/pull/1582](https://github.com/roots/trellis/pull/1582)

This earlier Trellis change would also solve this issue: [https://github.com/roots/trellis/pull/1558/files](https://github.com/roots/trellis/pull/1558/files)

Highly recommend getting some sort of SSL monitoring in place if you’re managing your own servers. I’ve been using [updown.io](http://updown.io) for about a decade and it’s super cheap. Use [https://updown.io/r/xcnzb](https://updown.io/r/xcnzb) if you want 100k free credits

The [roots.io](http://roots.io) server is a bit behind on Trellis changes and also had this issue. Got the heads up about it last night because of my alerts:
