Hi @bojan!
Thank you for getting back to me so quickly.
WPR Add-on version: 5.1.2
Pasting the report below.
Now, when you directed me there I see curl timeout is below recommended and there is SSL things, not sure if those could cause the issue.
We also use Wordfence addon in this network, that seems to be syncing fine. Other WPR settings are syncing back fine as well.
