Since 2026-09-10 ~14:30 UTC every pio remote command and every pio remote agent start fails with a continuous
[warn] Connection is lost to PIO Remote Cloud. Reconnecting
on two independent machines and networks:
- Agent: Linux ARM64 (Jetson), PlatformIO Core 6.1.19 under systemd, authenticated with
PLATFORMIO_AUTH_TOKEN. Restarting the service does not help; the log never reaches “Successfully connected” / “Authenticating”. - Client: Windows 11, PlatformIO Core 6.1.19 (also tried while it was 6.2.0 on 2026-09-10 – same result).
pio remote agent list,pio remote device listandpio remote run -t uploadall fail the same way, andpio remote agent starton this machine fails identically.
What I verified on my side:
pio account showsucceeds on both machines (Forever Free Remote Development package), so the account API and the credentials are fine.openssl s_client -connect remote.platformio.org:4413completes the TLS handshake (cert*.platformio.org, TLS 1.2 and 1.3) from the client network, so DNS, firewall and TLS are not the issue – the connection is accepted and then dropped at the protocol stage.- Nothing changed on our side between the last working session and the first failure.
Agent journal after a service restart:

Is there a service incident on the Remote Cloud? Happy to provide more diagnostics.
