We are experiencing packet loss to the IP WAN of our Core Meraki, the internet connection it's working fine, the strange it’s that we have our Meraki Core in HA and if we ping the secondary device there is no packet loss to the IP WAN, before this devices it is our ISP CPE where they bring us the IP Segment and there is another wan interface where is no loss, the only device that is losing packets it is the primary core, it is a very strange behavior. The other devices of our peers are working fine with the connection to the Core.   In this device we have two internet connections from 2 different ISP and the connection to Internet is fine, the problem is only with the Core Meraki Primary.   There are no changes in topology or infraestructure. The versión of our MX67 (peer) and MX250 (core) are MX 18.107. The problem began a few days ago, we have almost 3 years with the same equipment (core and peers) and this is the first time i ve seen something like this, this is different from the problems of our ISP's when there are packet loss/degradation on the Internet links.   We tried rebooting devices, turning off/on vpn, change wan links.   Here are the graphics of our device to IP WAN Secondary.   IP WAN Primary Connection to internet   Thanks for the help, if i can bring more information please let me know.     ...
