Hi, I’m using Mattermost self-hosted version for about 2 years already
Today, around 12h ago, my push notifications on mobile devices stopped working and I can’t understand why is it happened
Settings of the push-server it is, sorry that it’s in russian, but I think you got everything here, it’s totally default settings
Here’s an error from main mattermost container, I’m using docker-compose
{"timestamp":"2025-05-14 16:45:57.591 +03:00","level":"error","msg":"Failed to send to push proxy","caller":"app/notification_push.go:194","logSource":"notifications","type":"push","status":"not_sent","reason":"push_proxy_send_error","ack_id":"kmxuqimgwfnj3eajohcnxt96qe","push_type":"message","user_id":"eom4ud8siigginwx1zrts9n3br","device_id":"faf6c00e7a09053665d33186d82b24c680aacbf97aaf547c881182ca97115583","error":"unknown send response error"}
What we’ve tried so far:
- Checked the network connection to the Push Proxy
- We successfully ran a
curl
command from the Mattermost container topush.mattermost.com
and received a valid response.
- Verified the certificate
- We tried renewing the SSL certificates, both for the Mattermost server and the Push Proxy, to ensure there were no certificate issues.
- Mattermost Configuration
- Double-checked that the correct
MM_SERVICESETTINGS_PUSHNOTIFICATIONSERVER
URL was set in the Mattermost environment file.
- Reinstall the app
Despite these attempts, the issue persists, and notifications still fail to be sent with the error push_proxy_send_error
. This started happening without any changes to the Mattermost configuration.
- Has anyone experienced a similar issue where push notifications suddenly stopped working?
- Are there any known issues with the Push Proxy in the latest versions of Mattermost?
- Maybe some changes happened recently ?
I would appreciate any help or insights on how to resolve this issue. It’s so impornant.
Thank you in advance!
