Hey @niin,
Apologies for any delays here - Have you directly contacted our support team or raised an issue in our Github Issue Tracker, to alert the team of this problem?
As this is primarily the Postman Community forum, full of discussions about all things Postman, it can be difficult to see this individual topic and subsequent threads amongst all the other topics created on a daily basis.
If there is anything I can do to help out here, I’m available to do so. 
Thanks, no issue with any connections, but error remains for postman-cli
Thanks, I didn’t even know opening actual tickets were an option. All I ever found was the help forums
For others here, we ran across this problem in our enterprise and stumbled onto the fact that the newman flag --ssl-extra-ca-certs=path/to/cert.pem appears to work for the postman cli, even though it’s not documented.
The = may not be required, depending on your specific script. Both --param=value and --param value formats worked on my end.
It does not work for me. I try this command
postman login --with-api-key PMAK-…92 --ssl-extra-ca-certs=/etc/ssl/certs/ca-certificates.crt
and get error
error: unknown option ‘–ssl-extra-ca-certs=/etc/ssl/certs/ca-certificates.crt’
