@olivierlambert our opnsense resets the TCP states so the firewall block packet because it forgot about the tcp session.

And then, a timeout occured in the middle of the export.

Hello @olivierlambert

I confirm my issue came from my Firewall so, not related to XO.

However, it could be great to make logs more "clear", i mean:

Error: read ETIMEDOUT" 

Become

Error: read ETIMEDOUT while connect to X.X.X.X:ABC

That would permit to understand more quickly my "real and weird" issue

Best regards,
