Hi,
i receeiving sometimes while i try to push an update. error 500 "Failed to send an update."

log:
"class": "Symfony\\Component\\HttpClient\\Exception\\TransportException", "message": "Error:0A000438:SSL routines::tlsv1 alert internal error for \"https://domain.com/.well-known/mercure\".",

i use port 443. and after i start the mercure run with caddyFile the debug shows a certificate is active.

request>uri query {
replace authorization REDACTED
}
}
}
}
tls {

}
encode zstd gzip

mercure {
	# Transport to use (default to Bolt)
	transport_url {$MERCURE_TRANSPORT_URL:bolt://mercure.db}
	# Publisher JWT key secret
	publisher_jwt xxxx
	# Subscriber JWT key secret
	subscriber_jwt xxxx

    publish_origins https://domain.com
    cors_origins https://domain.com

    subscriptions
