Each hour, I got this log entry in my syslog
Apr 24 10:08:02 tailscale tailscaled: logtail: upload: log upload of 288 bytes compressed failed: Post “https://log.tailscale.io/c/tailnode.log.tailscale.io/18a…”: context deadline exceeded
It cause my tailscale to be inaccessible for two minutes but, more than that, it cause a drop in my entire network…
Hmm, I have no idea why that happens for you, but it looks like it happens when your Tailscale client tries to send logs to the Tailscale servers. Until you know why this happens, maybe you can try to disable the sending of the logs and see if that helps in the meantime.
Instructions are here: Logging, auditing, and streaming · Tailscale
Basically you have to either start the client with --no-logs-no-support or set the env var TS_NO_LOGS_NO_SUPPORT to true in /etc/default/tailscaled.
You Tailscale will still create logs, it just won’t attempt to send them to the Tailscale servers anymore.
