I also faced same issue. TAC has advised to try this.
As far as EDL warning is concerned, cert profile need to be configured to verify server certificate using CA that signed CA cert.
There are two ways to resolve warning
1) use http instead of https to connect to webserver in EDL config
2) Or, configure cert profile using root CA that signed web server cert, Global sign in this case and use it in cert profile under EDL.
