Created attachment 1756280 [details] silences 504 leads to "Not Found" Seen in 4.6. Maybe 4.6.16? I'll check. But due to compute-node issues, /api/alertmanager/api/v2/silences 504ed. Apparently because of that, the alert-listing logic was unable to list alerts, and it showed "Not Found" (screenshot attached). Ideally it would show an error message about the silence 504, to let folks know that the issue was "I don't know which unsilenced alerts match your filter", which is much more serious than "no unsilenced alerts match your filter, all is well". And it might also be worth listing all filter-matching alerts with some note about "maybe these are silenced, but we can't tell because the silences API is 504ing". Or maybe that risks being too distracting?
