Error 509 when connecting to Jira

[Toomas Adson]

When connectiong via api to Jira Cloud, I get following error:

https://projektid.atlassian.net/rest/api/2/instance/licence: tls: failed to verify certificate: 509: certificate signed by unknown authority.

Where to start with solving? Could the API key I created have issues?

Hi @Toomas Adson 

509 error indicates that there is a certificate/trust issue, not a problem with the API key itself. Possibly your TLS is failing to verify Atlassian's SSL certificate. It may be because that you are behind a corporate proxy or firewall which may be blocking the certificate or replacing with the self-signed ones.

So, I'd suggest (as @marc -Collabello--Phase Locked- mentioned) to visit that URL in your browser, if you get a cert warning, it means that the issue is with your local store.

Try to reach the URL from a browser and have a look at the response.

This will often help.
