[AMBER] Amber20 update failure on RHEL7/CentOS7

In our testing of Amber20, we found that amber_update will give an error on RHEL7 & CentOS7 systems:

./update_amber --update
NoInternetAccess: Cannot connect to https://ambermd.org<https://ambermd.org/>

We tried 5 different RHEL7 systems and saw the same error.

There is no such issue on other Linux systems we tested: RHEL8/SLES15/Ubuntu16/18/20.

I added a "print(str(err))" to the "has_internet_access" function in downloader.py and got:

<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:579)>

So this looks like a SSL certification issue on Amber server for RHEL7 & CentOS 7.

Is this a known issue?
