Suddenly the user mentions stop working on my instance.
When I'm adding a comment and start making a mention it show "Found no matching users for: XPTO" but when I inspect the page it makes a request to "rest/api/2/user/viewissue/search" and it return valid users.
How can i debug this further?
For us mention works occasionly, more like an "I'm lucky today"-feature than a reliable one. No Changes in notification schemes, no access rules Changes, still users don't get notified now and then. Starting to get a big problem here as we use mention feature a lot.
If this is a JIRA Server instance take a look at Mentions are not working in JIRA applications and follow the suggestions there. If this is a cloud instance take a look at Mentions and Autocomplete are not working in JIRA Cloud and let me know the results and we'll go from there.
If this is a Server instance, reproduce the issue and provide the log snippet from the time you get the error and we'll go from there.
I will take second look at the link you provide.
The problem is that i don't find any error.
