I absolutely loved ZeroTier for last 4 yrs.

Until 2 weeks ago when my Windows machines absolutely stopped seeing each other and communicating with each other.

I made a post on ZeroTier discussion group 2 weeks ago with zero replies so far: https://discuss.zerotier.com/t/windows-machines-lost-access-...

If i can get some help - would be amazing.

Had something maybe similar too - some times instant connecting, sometimes slow, sometimes 0%. Fixed and happily using ZT every day now. (TY ZT!)

On both computers do: Network connections->Right click ZT network->Properties->Select (TCP/IPv4), probs 5th down. ->Properties->Advanced->Untick automatic metric-> set interface metric value to 1. Potentially reboot, though I've not needed to before.

Just for some visuals if needed https://support.parsec.app/hc/en-us/articles/115002766652-Us...

not a lot of detail in your post.

have you worked through: https://docs.zerotier.com/zerotier/troubleshooting/ ?

Yes. Didn't help.

However suddenly one laptop was able to connect to 2 other windows boxes (even though other Windows machines cant).

This tells me it's not ZT fault, but rather everlasting update and restriction nonsense from windows is a culprit

Pretty much this ^^ You've given no detail that differentiates your issue from all the other general troubleshooting advice out there already, nor do you say what you've tried to debug it.
