#5021 Let's Encrypt .. .. request failed : Web-based validation failed :

[Marc LAURENT]

Dear Community,

I'm running :
Operating system CentOS Linux 7.4.1708
Webmin version 1.852
Usermin version 1.720
Virtualmin version 6.00
Theme version Authentic Theme 18.49-9

since an upgrade of the system that is fully up to date (Package updates All installed packages are up to date ) the Let's encrypt certificate request Certificate outputs an error.

I'm using the Virtualmin interface : Virtualmin > server configuration > manage SSL certificate > Let’s Encrypt

the error is:

Requesting a certificate for dsd.fr, www.dsd.fr from Let's Encrypt ..
.. request failed : Web-based validation failed :
Traceback (most recent call last):

Does anyone know what this problem could come from ?

Thanks

Seems like your system is missing the cryptography python module?

[David Merinas]

This is what I did to fix the error:
pip install --upgrade pip
pip install --upgrade cryptography

[ghemit yasser]

not works for me

[Jamie Cameron]

That works ... also, there is a python2-cryptography package you can install from YUM.
