How do we by pass this issue with SonarQube server v5.1 and firefox? Chrome & IE are working fine but firefox is not allowing to access the server in https mode. I looked at https://weakdh.org/sysadmin.html but I am not sure what server SonarQube uses and how to implement fix for this problem. Any help is appreciated. Thanks.
When a user wants to enable (or restrict) access to a SonarQube instance over HTTPS, the recommended way is to put it behind another WebServer she configures at will.
So, the way to go here, is to add an Apache, Nginx or whatever in front of the SQ instance and configure it according to the recommendations in the link you provided and generate a "safe" server certificate.
