In the end, after many unhelpful tech support calls, I bailed from Vodafone and swapped to Zen. Who knows what Vodafone were doing down the backend of their system, but on Zen my server is back to working absolutely fine. If you have a similar problem and find this thread, then I'm sorry I never fou...

We've never actually had anyone connect that didn't already have the mods installed but presumably the sync function will take care of all that. If anyone wants to give it a go, I've made a backup so can leave it on. Address is: factorio.arpc.co.uk Time of day hasn't made any difference. After some ...

Ok so, as you said I've tried it on a different machine with a new .zip of 1.1.87 with only the save and mods changed. Hosted as a "normal" in-game server, not headless client. Issue persisted. The map download speed seemed to hit exactly the same limit around 400 kBps. Going to have a go ...

Hmm, I can get them to double check. This is occuring across multiple clients though, who have had no changes to their firewalls since it stopped working. I'd have presumed it was something on my end not theirs as I'm the one that's had a big switch in conditions.

Unfortunately this doesn't seem to have fixed the map download pr...

Yeah, that makes sense. Thanks for looking into it so quickly. There might not be anything I can do about it on the Factorio side, but I've only just switched ISP's so I've time to contest it/drop out of the contract. Happy to mark this one as complete but as a last part in case anyone else finds th...

I have noticed my latency and packet loss will jump occasionaly when playing other games, but if that was the issue I'd only expect the map download rate...

Thanks for the quick reply. I'm attaching 3 logs. One for the server, one from myself (who can connect) and one from my friend (who can't connect) I am running a second 1.1.87 zip instance of the game as my client. If I join using my local IP, I can download at around 30MBps, presumably a read/write...

Hi, My friends and I have been working our way through a Space Exploration save for a few months which I have been hosting as a headless client from a .zip version of 1.1.87. This has been running quite happily with people joining the serving downloading the map at around 3MBps via my public address...
