We are currently on Jira software version 8.13.2 and need to upgrade. After we upgrade to 8.20, everything appears to work as long as we are connected to the VPN and accessing Jira. If we disconnect from the VPN and access Jira (which works fine on our current version) when we go to log in we just see a blank page. We have noticed that if ScriptRunner is disabled, everything works fine again.
Another thing we noticed is that on our current version of Jira, if we are not connected to the VPN we cannot view BigPicture - it does the same thing where you just see a blank page.
Was just wondering if anyone else has experienced anything similar before or has any troubleshooting suggestions.
