Hello
I am getting the following errors filling my system log to a point where the internet stops working and I need to either reboot the router or turn my VPN client on/off

For reference, XX.X.X.145 is my desktop computrer and the ports seem to be from Apollo Sunshine client. The issue started recently and I haven't been able to find a solution to this

@mehravishay, it may help provide context if you provide more information about your setup and what troubleshooting steps you've taken.
What is your router model?
What firmware version are running on the router?
What is the VPN service the VPN client is connected to?
What is that desktop computer doing or how is it being used (what program/software) at the time those errors show up in the router log?
What happens if you turn off or disconnect the desktop computer from the router, does the errors persist?

Hi
What is your router model? Asus GT-AXE11000 and an Asus RT-AC86U used as a mesh AP. The PC is connect to the mesh AP via a network switch
What firmware version are running on the router? Merlin 3004.388.8_4 on the AXE11000 and 3004.386.14_2 on the AC86U
What is the VPN service the VPN client is connected to? Wireguard via Proton VPN
What is that desktop computer doing or how is it being used (what program/software) at the time those errors show up in the router log? I believe the software causing the issue is Apollo Sunshine. Its basically my gaming computer I use to stream games remotely so there is no active usage unless I am gaming. However quitting the app does not seem to solve the issue.
What happens if you turn off or disconnect the desktop computer from the router, does the errors persist? When I disconnect or turn off my PC (something I started doing after the issue occured) the issue goes away.
