Horizon and Wirecloud run on the same apache, Wirecloud under port 443 and Horizon under port 40443. Both use the same cert files for ssl and work, called by themself, fine. Those cert files are currently self signed ones.

Since I am pretty new to ssl usage in apache any halp would be much appreciated.

As you are using self-signed certificates, the best option is including your cert into the list of trusted certificates. requests (the module used for making this request) usually uses a bundle by default (it depends on the installation method). You can edit that bundle for adding your cert (see this link for more details) although you will have to update this bundle every time you upgrade the requests module.

Another option, is to configure requests for using the trusted certs repository from the OS. This can be configured using the REQUESTS_CA_BUNDLE environment var (e.g. by editing your wgsi.py file adding something similar to this: os.environ['REQUESTS_CA_BUNDLE'] = "/etc/ssl/certs/ca-certificates.crt"). The operation of adding your cert into the trusted repository depends on your OS, but there is a lot of information about this matter on google (e.g. here you can find how to do it using Debian/Ubuntu).
