Quick one today, but one that stole more time then it should have away from todays project.
In Postman if you are working locally on something like a REST API without a valid SSL certification setup Postman will fail to perform requests often failing with one of the following messages:
Error: unable to verify the first certificate
Error: socket hang up
The workaround to this is to disable SSL Verification (File->Settings->General->SSL Verification
).
