Push notifications not working on mobile

Troubleshooting
1

Hello.

I installed Mattermost via Docker using the included NGINX. Everything works fine except for the push notifications on mobile phone.

When I log in on my phone, I see this warning message:
2024-01-26_10-31-23

Push notification settings:

2024-01-26_10-33-54
2024-01-26_10-33-54903×284 27 KB

Log messages:

Please tell me what I have to do to make it work properly. Thank you!

See if Mobile apps FAQ — Mattermost documentation helps.

Thank you. Documentation didn’t help.
I ran this script in container shell and didn’t get any response

curl https://push-test.mattermost.com

ran this command:

sudo docker exec -ti c9ffed7a844e curl -v https://push-test.mattermost.com

What does openssl s_client -showcerts -connect push-test.mattermost.com:443 </dev/null return?

6

ran this command in mattermost docker container:

sudo docker exec -it 36b3066f6195 openssl s_client -showcerts -connect push-test.mattermost.com:443

output:

CONNECTED(00000003)

and nothing else…
