# Self-signed certificate

## **Self-signed certificate** <a href="#self-signed_certificate" id="self-signed_certificate"></a>

Jira can be configured to support secure connections via HTTPS. In this case, all HTTP requests are redirected by Jira to HTTPS. When a self-signed certificate is used by Jira, the Jira sync and also the sync configurator can no longer connect to Jira, as they will reject the self-signed certificate. The certificate must be marked as trusted on Windows to allow the Jira sync to connect. This can be done as follows:&#x20;

* Open Internet Explorer
* Navigate to the Jira URL
* Click on Continue to this website
* Click on Certificate error in the address bar
* Click on View certificates
* Switch to Details tab
* Click on Copy to File
* Select DER encoding
* Click on Next
* Select jira.cer as filename
* Click on Next and then on Finish
* Open MMC (win+r, mmc)
* Click on File and then Add/Remove Snap-in
* Select Certificates and click on Add
* Select Computer Account
* Click on Next and then on Finish
* Click on OK
* In the tree, right click on Trusted People
* Select All Tasks and Import
* Click on Next
* Click on Browse and select the certificate you saved earlier
* Click on Next and again on Next and on Finish

Afterward, you can reopen Internet Explorer and navigate to the Jira URL again. Now, no certificate warning should be shown. Please note, that it is important to install the certificate to the Computer Account. Otherwise, your current user account will trust the certificate but not the service account which runs the aqua backend.
