SSL verification error at depth 3

I'm trying to install vagrant hostmanager using this command but this error keeps showing:

 $ vagrant plugin install vagrant-hostmanager
Installing the 'vagrant-hostmanager' plugin. This can take a few minutes...
ERROR:  SSL verification error at depth 3: unable to get local issuer certificate (20)
ERROR:  You must add /C=US/O=Starfield Technologies, Inc./OU=Starfield Class 2 Certification Authority to your local trusted store
Vagrant failed to load a configured plugin source. This can be caused
by a variety of issues including: transient connectivity issues, proxy
filtering rejecting access to a configured plugin source, or a configured
plugin source not responding correctly. Please review the error message
below to help resolve the issue:

  SSL_connect SYSCALL returned=5 errno=0 peeraddr=18.66.196.18:443 state=error: certificate verify failed (https://gems.hashicorp.com/specs.4.8.gz)

Source: https://gems.hashicorp.com/

i tried these options:

• export SSL_CERT_FILE=/etc/pki/tls/certs/ca-bundle.crt
• installing the Starfield Technologies certificate directly to my computer but nothing works

having this problem as well, did you ever figure it out?

Only workaround I've found is to downgrade vagrant to version 2.3.4

Turns out that vagrant isn't allowed in my country so a vpn worked for me
