As you can observe from the error message above the connection was blocked because the certificate supplied did not match the name of the host. I wasn’t sure why 1e100.net was being used and I was worried it might compromise my security. However further research showed it is a Google owned domain and it is legit. Below is the answer I found on the Google website about it:
Answer obtained from Google:
Following standard industry practice, we make sure each IP address has a corresponding hostname. In October 2009, we started using a single domain name to identify our servers across all Google products, rather than use different product domains such as youtube.com, blogger.com, and google.com. We did this for two reasons: first, to keep things simpler, and second, to proactively improve security by protecting against potential threats such as cross-site scripting attacks.
Most typical Internet users will never see 1e100.net, but we picked a Googley name for it just in case (1e100 is scientific notation for 1 googol).
If you do some further research, you will see that in fact the IP addresses that the domain 1e100.net are owned by Google. Below is an example from the IP referred to above:
