That error appears in the certificates screen so (I'm assuming) it's independent of the TrueCharts release. Regardless, I pulled in the new stable/incubator train as well before I began just to be sure.
Don't assume.
The old version of TrueCharts should
NOT be used with 21.02, as it contains it's own ACME system which might in fact conflict with the one integrated into TrueNAS.
Gave up after about an hour or so. Going to wait & try again after the official 21.04 release.
Unless there is an emergency patch because people
ACTIVELY report this right away, there is
NOT going to be any change to this on official 21.04. The release is in
codefreeze, so unless you can convince iX with
bugreports that this is a priority issue that needs to be fixed, it is
NOT going to be fixed at 21.04ALPHA release.
Ok, thanks. Maybe it is not a configuration problem with my setup. I will wait as well before reporting a bug.
If you want ANY chance of a fix before 21.04, I would submit a bugreport ASAP!

I've manually gone through the iX code and compared it to other implementations of Certbot using Python.
I've found some "not-so-nice" code, which I already know because I wrote the errors you guys are getting :P
But nothing majorly wrong.
The problem is that these issues tend to
magically fix themselves.
So the hard part is getting debugs, so
PLEASE submit as many debugs about this to iX as possible.
If you can also try to add screenshots of your settings so iX can cross reference those with the Debug.
In the defence of iX:
The documentation for certbot and, primarily, the lack of any "reference deployments", is complete and utter crap.

I've also updated the TrueCharts certificate documentation to now include some general advice and troubleshooting steps if Letsencrypt/ACME instabilities hit you.
