I’m currently using zerotier v 1.62 on an Apple Macbook air, M1 chip, using macOS Big Sur 11.1.
Everytime I turn on my mac, the network starts slowing down after a few minutes.
The slowdown is not in terms of pages loading slowly, but they don’t load at all, then time out, with a host not resolved error. Refreshing the page, the page may or may not load, but if it loads, it loads at full speed.
Usually, when it get’s stuck, i see ‘resolving host’ in the browser status message.
This behaviour affects ALL clients on the network, windows pcs etc.
It seems as though my macbook’s zerotier client is exhausting all avaliable tcp connections on my LTE router.
Even as I am unable to load some pages, other pages that already streaming a video, youtube, for eg. continue to stream the video with no problems.
After 2 days of investigating, I noticed that the problem disappeared within a few minutes of turning the zerotier client off on my macbook.
I am able to consistently reproduce this issue.
Zerotier clients on windows do not cause any problems on this network, just my mac.
