[0.17.3] Can't connect to redmew servers in multiplayer

[turk127]

First tested on version 0.17.03, but it could be from 0.17.1. When trying to establish connection to any redmew sever in multiplayer either via browse or direct connect I get the "Couldn't establish network communications with server" error.

Having worked with redmew, we did a large number of tests, and a number of network packet dumps. I've include the factorio player log, but not the packet dumps. The server is sending the complete ban list log files back to client and the client is just viewing the above error. The data being sent back from the server is being ignored by factorio as well (it appears client is not handling bad data formats in a way client can understand). This might be two separate issues.

I have tried renaming username, fresh install, an empty redmew server, turning off IPv6. The connection is from Australia to Germany. My ISP is one of the largest ISP's. I don't have issues with any other server and I can also connect to redmew's webserver on same address (different port)

We have packet dumps from both the client and the server, I've not included them as they contain the complete ban logs. If I were to guess I would look at the variable sizes and if there has been a change as it appears one module has had a buffer overflow and is dumping the complete logs into the stream.


If you want the packet dumps please let me know I can email them or make them available directly.

I have exactly the same problem, cannot join Redmew servers since upgrading to 0.17.0 and till now 0.17.14.

PS 1: I could join and play a lot on Redmew at 0.16.51, without issue.
PS 2: I can join other public servers at 0.17.4 till now 0.17.14, without issue. So I guess not my router nor firewall problem.

In recent version 0.17.33, I can finally join the Redmew servers.
Perhaps some "hidden" changes are made.

You may try joining those servers again.
