Sessions not properly closed?
« on: December 15, 2020, 01:42:30 pm »
I've got a PV inverter form Solaredge.
This works great. It sends his data to the cloud on regular base. And does this for over 3 years now.

But the last 3 months, after opnsense upgrade/change of settings..., the data is blocked sometimes (approx 2 weeks?)
When I reset the 'states' (firewall > diagnostics > state reset), it works again without any further manipulation.
I didn't notice other simular problems. At this point, only the PV inverter has connectivity issues.

Any tips what I should check to debug this?

I've reinstalled my opnsense firewall, and had the same issue. My solaredge PV intverter stopped sending the data after a while.
And I had to search again for the solution. So for that, hereby the solution:

  • Go to FW rules
  • Select the interface with the network of your PV inverter
  • Edit the rule: Default allow LAN to any rule
  • Show 'advanced options'
  • State type, choose 'sloppy state'
