The requested address is not valid in its context. (os error 10049)

I am getting this error when trying to start lazymc on Windows: "The requested address is not valid in its context. (os error 10049)".

Basic research online seems to indicate it is to do with the local IP, so I have targeted the local IP and port field on line 27 of lazymc.toml. However no matter what I try in this field I cannot get around this error. I have tried 127.0.0.1, localhost, the machine's local IP on the LAN, even my public IP. I have also ensured the port is different from the public port, and that the port I put here matches the port set in the server config file. Lazymc still returns the same error every time. I'd love to use verbose mode to get more info but I can't seem to add that to the startlazymc batch file in a way that doesn't also produce an error about --verbose not being expected.

I'd also love to review the configuration page referenced in the Windows usage info, but that page 404s.

I have tried generic solutions from online like flushing dns.

That is super weird! This might be a more general OS error outside of lazymc itself. I've not seen it before.

Do you also see this when listening on a public IP address, or when using other software?

You can find the configuration reference here: https://github.com/timvisee/lazymc/blob/master/res/lazymc.toml

Thanks for your quick response. I'm continuing to investigate whether it's something on my system. I think I could probably gain a lot, though, from getting the program to run in verbose mode so I could possibly get a better idea of where it's encountering a roadblock. I'm sure it's something silly, but could you advise on how I should be configuring the startlazymc.bat file? Among others, I tried:

.\lazymc.exe start --verbose pause

Where pause is on line 2.

But that returns the following:

error: Found argument '--verbose' which wasn't expected, or isn't valid in this context

  If you tried to supply `--verbose` as a value rather than a flag, use `-- --verbose`

USAGE: lazymc.exe start [OPTIONS]

I tried its suggestion, which also didn't work.

To answer your questions, I haven't encountered this error before. For some context, the machine runs both a Valheim dedicated server, and heavily modded Minecraft server, but isn't used for much else, so it's possible I haven't done enough things on it to find out about this problem until now.

Many thanks!

So it turns out it was a mistake on my part. I shall explain, in case anyone else does what I did:

I put my public IP address and the port users use to connect in line 16. I put my local IP address (127.0.0.1) and the server's port on line 27. As we know, I then got the error. My research online told me that this error has to do with the local IP, so I thought I must have done something wrong on line 27. It turns out that I had actually made a mistake on line 16, the public IP. Leaving it at 0.0.0.0:xxxx was the solution, which I discovered by regening the config file and starting anew.

At this point I had gotten around the error and was off to the races. The only other issue I encountered was previously documented by Wiiinterr and solved by supitsmike here: https://github.com/timvisee/lazymc/issues/25

It's working perfectly now and I'm thrilled, as this will save a lot of wasted power. Much appreciate the nifty software and your responsiveness as a dev when I raised my self-inflicted issue.

Oh yes, that makes sense! Sorry I didn't catch that. It may be possible to add a specific error for this, hinting users to set their IP properly.

Happy to see you got it to work!
