Error message

read body

What it means

Raised in Updater.getLatestRelease when io.ReadAll fails while reading the (size-limited) response body of the GitHub releases response — the connection dropped or was reset mid-body. Without the full body, the release JSON cannot be parsed and update detection fails.

Solutions

1. Retry the HTTP request, since interrupted connections are usually transient
2. Check that DownloadBytesLimit is not set so low it truncates and breaks the read
3. Verify network stability (proxies, VPNs, flaky Wi-Fi can reset connections mid-transfer)
4. Increase any client-side or proxy timeouts that might abort long reads
