That's unusual - which Perl version are you running there? Also, which version of the Net::SSLeay perl module?

[alex p]

Perl is 5.22.1
OpenSSL is 1.02g

But how can I check the version of the Perl module?

Sorry, not an expert for Perl :)

[Jamie Cameron]

You can see this at Others -> Perl Modules in Webmin.

[alex p]

Ok .. but Webmin is not starting .. so I can not see any information in Webmin :)

[Jamie Cameron]

As a work-around, you can disable SSL by removing the line ssl=1 from /etc/webmin/miniserv.conf

[alex p]

Ok, I found it.

This is the modules version: 1.72-1build1

[Jamie Cameron]

Ok, that looks pretty recent. How did you generate the SSL certificate on this system?

[alex p]

I didn't .. it's a clean install as it usually works from scratch.
I reinstalled the package (webmin) as the installation before stopped to work overnight.

Run into the same issue I think (after updating plesk) - I inserted the statement

print Net::SSLeay::ERR_error_string(Net::SSLeay::ERR_get_error());

before that line and got this:
error:140A90F1:lib(20):func(169):reason(241)

and 'openssl strerr 140A90F1' says:
error:140A90F1:SSL routines:SSL_CTX_new:unable to load ssl2 md5 routines

Possibility reasons are:

• the openssl was not build with certain support
• some routine must be called before (or not) with never library versions
