Tried again and it returned a somewhat different (Python) error:

You have a missing python module try

sudo pip install cryptography --force-reinstall

So Laravel Forge apparently did something on their end that fixed the Python issues...but now I have a new issue. Trying to install LetsEncrypt SSL now results in this error:

--2018-11-19 18:42:14--
Resolving ( failed: Temporary failure in name resolution.
wget: unable to resolve host address ‘

That "temporary failure" has been going on all day, so I suspect that it's not truly temporary.


Same here. The "temporary failure" has been going on all day... showbox
