Comments for files from android app

When I try to view comments for files via android app (f-droid, 3.14.0), I get error: "Operation finished with HTTP status code -1 (fail). But add comment is work, I see it over web interface.

Server version: 19.0.5

When I request comments for file in nextcloud.log:
