SABnzbd Forums

Hi post my upgrade to ubuntu 18.04

Sabnzbplus complains of this error

Anyone else having this issue?

My guess: in .sabnzbd/admin/ move server.cert and server.key away. Then start SABnzbd again.

Thanks that worked !!

Nice.

Cause: an old SAB created your cert/key a long time ago, and current Ubuntu considers the key (?) too low security. After you delete them, SAB will create a new cert/key, with higher security settings, and Ubuntu is happy again.

This solution also helped me.
