Hi,
we blocked all incomming UDP except DNS 🙂
loopback is not blocked. We block on notworklevel (before the data even reached the data center).
Thats the confirmation I hoped for. It doesn’t make much sense that a plugin should communicate over UDP at all. With this answer we can focus our manpower to search elsewere for the problem.
Thanks.
Hi.
We disabled UDP-incomming traffic on the network backbone (We are a webhoster for hundreds of servers).
After this action our customers who use the yoast seo plugin can not longer activate the yoast license.
