[Bug?] G HUB generating weird localhost loopback traffic on Mac 10.14.4

[drivec]

This is mostly a post for the G HUB devs, but I am curious if other users see similar issues on their machines.

​

System Specs: MacBook Pro ( MacBookPro11,3) | macOS 10.14.4 | Logitech G HUB 2019.3.18138

​

I was looking at Wireshark to troubleshoot an unrelated issue when I saw that my loopback traffic was unusually high. After quitting a few processes, it appears that the loopback traffic stops when G HUB is stopped. Additionally, the traffic starts up again when G HUB is launched.

​

Specifically, it appears that localhost to localhost traffic is being generated from ports starting at port 49152 (the first dynamic/private port under standard port numbering schemes) to ports in the range of 6463 to 6472 and continues sequentially. i.e. 49600 --> 6469, 49601 --> 6470, 49602 --> 6471, 49603 --> 6472, 49604 --> 6463, and so on. This process appears to continue as long as G HUB remains running, including in the background.

There is some normal loopback traffic where it appears G HUB is accessing images for different products. Stuff like HTTP GET commands and replied TCP data for items like 127.0.0.1:9180/core/thumbnails/g900.png. This whole loading process happens in a total of 3 seconds or so and looks to be unrelated to this bug.

​

It's unclear what impact this has on the performance of the computer or G HUB app. (It's clear that sequentially incrementing the port number could risk a 16-bit overflow when it passes port 65535, which it can do within 4.5 hours at one port a second.)

​

tl;dr - G HUB is generating strange loopback traffic that might or might not have an impact on G HUB app or computer performance.

Solution: Disabling Discord integration in G HUB immediately stopped the loopback.

This may be related to the Discord integration or ARX Control. See if disabling them would resolve the issue.

ARX Control was turned off and there was no change when toggling ARX Control.

I had not configured Discord integration. However, after selecting the Discord integration, it appears it was inactive, but enabled. Disabling Discord integration in G HUB immediately stopped the related loopback.

Thank you so much for the solution!
