ERROR: [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:997)

[Jeff Johnson]

Getting this error when using GAM on our prod network that has MitM policies. Tried implementing the GAM_CA_FILE for our PEM file, but not working. Are there other URLs we need to allow besides accounts.google.com and *.googleapis.com?

• I have upgraded to the latest GAM release from https://git.io/gamreleases and I still have this issue.
• I am typing the command as described in the GAM Wiki at https://github.com/jay0lee/gam/wiki

Full steps to reproduce the issue:

1. gam info domain

Actual outcome (what errors or bad behavior do you see instead?):
ERROR: [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:997)

Try also setting the minimum required TLS version to 1.2. default is to require 1.3 but your prod network may not support that.

export GAM_TLS_MIN_VERSION=TLSv1.2
