Exactly at 0:00 tonight, my monitors in Uptime Kuma started to report downtime. Log told me either “timeout of 48000ms exceeded” or “getaddrinfo EAI_AGAIN”, despite the actual websites all being online.
I changed DNS settings from Quad9 to dns0.eu, nothing changed. Updated from the current release version to v2 beta 3 (because I already wanted it before), nothing changed. Changed the DNS settings to my local AdGuard home – everything’s fine now. 🤔
Why? 😄
