**Summary**  
After upgrading, custom emojis are missing. Requests to https://\<my.server\>/api/v4/emoji//image are 404’ing.

**Steps to reproduce**

- Server running Ubuntu 22.04
- The upgrade was from 9.11.6 → 10.3.1, I likely did not look at the output of [step 7](https://docs.mattermost.com/upgrade/upgrading-mattermost-server.html) of the upgrade guide clearly enough.
- I see little of interest in logs

**Additional details**  
I’m unclear how to restore the image files as I use S3 for file storage, and had thought emojis were stored there.

I have an old server backup with the `emoji` folder preserved with the correct emoji id’s that I’d prefer to restore so as to not need to manually re-upload every emoji (and lose the emoji history if I have to delete the old emojis), but I’m not sure where to restore it to.

I’ve tried restoring the files into `/opt/mattermost/client/emoji/<id>/image` and also `/opt/mattermost/data/emoji/<id>/image`, but it doesn’t seem to fix the issue.

Any help is appreciated!

I’ll look into this a little.

Hmmm okay I managed to fix this, but I’m not sure how I did it. I suspect something broke in my S3 connection, even though I thought had tested the connection.

Something in the following steps resolved the issue:

1. Changing from S3 storage → Local file storage → back to S3 storage
2. Fiddling with S3 connection parameters until it was green again
3. Purging all caches within System Console
4. Manually restarting the Mattermost service with `sudo systemctl restart mattermost` a couple of times
