Push Notification Fails "because of missing server Id"


I think I set something up wrong way back in the beginning and I have a baaaaad feeling that it won’t be easy to fix. Push notifications are not working and fail consistently with an error.

Recreation Steps:

  1. User 1 logs off of all instances of Mattermost
  2. User 2 logs into Mattermost and sends a private message to User 1

Actual Results:
Email notification works as expected; however, push notification not received. Log shows error like this:
{“level”:“error”,“ts”:1534026496.377071,“caller”:“app/notification.go:871”,“msg”:“Device push reported as error for UserId=som9ztfzqjyyjg39rb45y9k55y SessionId=hrkg31w54pdcudekr6cddqkmqe message=Failed because of missing server Id”,“user_id”:“som9ztfzqjyyjg39rb45y9k55y”}

Expected Results:
Should be able to receive iOS push notifications

./mattermost version
Version: 5.0.0

iOS 11
App Version: 1.10.0 (build 127)

Does this mean that I need to downgrade to Team Edition? This page (https://docs.mattermost.com/overview/faq.html#how-does-mattermost-scale-from-teams-to-enterprises) talks about being able to, but I haven’t found any instructions detailing that. Thanks in advance for everyone’s help!


Hi @testerson - Thank you for reaching out!

Does User 1 get push notifications when they are logged in? I believe users need to be logged in to receive push notifications.
