I was following the instructions on this page: https://doxfer.webmin.com/Webmin/Securing_Webmin to secure my webmin installation but I got the error SSL_ERROR_NO_CYPHER_OVERLAP when trying to access Webmin. there is another forum post that is similar to this (https://www.virtualmin.com/node/38602#comment-form) but it did not fix my issue.
pls close this. i solved this
It would be of help to other users if you explained to us how you solved this.
I just managed to hose my virtualmin certificate by copying what turned out to be a broken domain cert to webmin in the web GUI and tried to fix in via ssh by doing:
virtualmin generate-cert --domain mydomain.com --self
virtualmin install-service-cert --domain mydomain.com --service webmin
which changed the initial error from (lost it exactly, something to do with key too long) to SSL_ERROR_NO_CYPHER_OVERLAP so trying to fix that. I tried the “comment out ssl_cipher_list line” from that post and restarted but no joy.
Any other clues @bhaberman?
In the end i managed to recreate my miniserv.pem from the public cert and key using similar commands to the instructions here https://www.digicert.com/ssl-certificate-installation-webmin.htm
Hope that helps someone else, looks to me like the virtualmin generate-cert doesn’t create valid certs
