A slow upstream creates an unlimited queue behind a finite connection pool.
Estimated field mix
A cancelled report download continues consuming upstream bandwidth.
Estimated field mix
The proxy retries a POST after its connection breaks, potentially duplicating a write.
Estimated field mix
Buffering simplifies upstream retries but large reports exhaust proxy memory.
Estimated field mix
Configuration reloads close active report streams immediately.
Estimated field mix
Operators need to distinguish header rejection, pool waiting, and upstream disconnects.
Estimated field mix
A certificate signed by the internal CA is accepted for any service name.
Estimated field mix
A workaround accepts self-signed certificates by disabling all verification.
Estimated field mix
Renewal is noticed only when connections begin failing.
Estimated field mix
Long-lived connections keep using the old client identity after new credentials are loaded.
Estimated field mix
Handshake errors include large diagnostic objects containing sensitive material.
Estimated field mix
Routine renewal should not require every client to restart simultaneously.
