Error creating interface: Cannot create a file when that file already exists #955

Closed socram8888 closed 1 year ago

socram8888 commented 2 years ago

I'm having some issues when restarting the Yggdrasil 0.4.4 service under Windows 10, x64.

Sometimes it works and creates the interface right away after restarting. On other occasions, the interface is not created, and about 10 seconds later this error pops in the log:

Apparently it has something to do with device creation/deletion, as I can see this error popping up on C:\Windows\INF\setupapi.dev.log:

It seems that, if I manually remove the device and drivers using devmgmt.msc left after the tunnel is shut down, the service always starts reliably. Otherwise, it exhibits this seemingly random behaviour.

Looks like it's the same reason why I stopped updating my Yggdrasil installation: #891

socram8888 commented 2 years ago

I've just tried 0.4.5, which reading through the changelog has better cleanup, but still has the same issue.

Fixed in RiV-mesh

Please reopen if this is still an issue on v0.5 release candidates.
