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 in Windows to allow the Jira sync to connect. This can be done as follows:
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
Afterwards, 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.
