Failed to save SSL options : The SSL private key file /etc/webmin/miniserv.pem does not exist or does not contain a PEM format key
Everytime I try to save SSL options in webmin (Webmin tab -> Webmin Configuration -> SSL Encryption -> Save) it spits out the above error.
I’ve tried with a fresh operating system install three times, Self signed certificates, and the default webmin certificate, lets encrypt certificates.
No matter what PEM i point it to, it complains its not correct format. EVEN with the default certificate webmin itself creates on initial install.
Operating system: Debian Linux 9
Webmin version: 1.860
Usermin version: 1.720
Virtualmin version: 6.01
