Blokli instance doesn't work behind a DNS CNAME

[QYuQianchen]

The applications using blokli whose DNS record name is a CNAME does not work as if the DNS record name is A.

Testing:

• Create a DNS CNAME record that points to what ever other blokli instance
• Start a hoprd node pointing to the DNS endpoint instead to the original endpoint
• The node fails getting data from blokli just at the beginning.

I've checked the following scenario:

• Created DNS CNAME record blokli2.jura.hoprnet.link pointing to blokli.jura.hoprnet.link
• Make example request in blokli-inspector: blokli-inspector -u https://blokli2.jura.hoprnet.link query safe -a 0x0CDecAFf277C296665f31aAC0957a3A3151B6159
• Got this error:

Error: error sending request for url (https://blokli2.jura.hoprnet.link/graphql)

Caused by:
    0: error sending request for url (https://blokli2.jura.hoprnet.link/graphql)
    1: client error (Connect)
    2: The certificate was not trusted.

• By executing the same command against the original blokli DNS name, works
