BAD_SIGNATURE or signature_invalid while creating Stash to JIRA application link

With Stash 2.5.0, if you create an application link with JIRA (2.5.11 for instance), then "Application 'Your Company JIRA' seems to be offline. Click here to Relocate." is displayed in the Configure Application Link GUI. Then in the STASH logs there is "signature_invalid" or "BAD_SIGNATURE".

The same is working as expected with STASH 2.4.2
