[SOLVED] Cannot enable HPNS mobile push notifications

We’re running a self-hosted instance of Mattermost 4.3.0 with an Enterprise E10 license. I’m trying to enable mobile push notifications. On System Console -> Notifications -> Mobile Push, I select “Use encrypted, production-quality HPNS connection to IOS and Android apps” from the dropdown, check the Terms and Conditions box and hit Save.

However upon hitting save, the dropdown box reverts to “Manually enter push notification service location” and my selection is not saved.

Any thoughts?

Thank you.

This was a bug in the system console for our 4.3.0 release, upgrading your server to the newest one should resolve this issue
