It is not purely my system causing the connection issue, since I am able to read the server list JSON in my browser (at multiplayer.factorio.com).

I attached the log file and a screenshot of the error message.

There are several suggestions for this (or a very similar) issue ...

A couple of days ago, I joined a friend's multiplayer game. At first, I was not able to join, but then I learned that I had to open port 34197 (and choose UDP). That ...

You can set the multiplayer compression to be higher, but it still doesn't make a huge difference in save size. There's a finite amount saves can be compressed and with the ...

For autosaving I'd say keep current compression level but for multiplayer it would be nice to have higher compression and for manual save maybe max compression?

Switch 2 Factorio stuck on 2.0.72 — unable to load multiplayer save created on PC 2.0.73

Hi Factorio team,
Could you please update Factorio on Nintendo Switch 2 to the same version currently available on PC?

Right now, the Switch 2 build is 2.0.72, while PC is 2.0.73. This small version mismatch has a real impact: my friends who play on PC opened and saved our shared world on 2.0.73 ...

Re: Appreciation for better car snapping

Confirmed this is makes driving on straight "roads" much easier and doesn't interfere with any off grid driving that I've seen.
