@jburleson Yes both firefox and chrome uses the windows cert store as Tom posted. I know because we had to do this with our vCenter servers. You need to take the public root certificate of the self signed certificate and import it into the machine’s trusted root certificate store. Once you do that then there is no warnings in any of the three browsers.
While these instructions are specific to vCenter the process would be the same for any self signed root certificate. https://tinkertry.com/how-to-get-rid-of-vsphere-browser-certificate-warnings-in-windows
@tgidwani Ahhh, I see, got that wrong, sorry. I will take a look at our code again to see if I can figure out what might be causing this.
Just to be sure, Do you still get the full list of exact same ftp_… messages in the log everytime even when SELinux is disabled/permissive?
