https://bugs.winehq.org/show_bug.cgi?id=53346 --- Comment #20 from Olivier F. R. Dierick <o.dierick(a)piezo-forte.be> --- Hello, Someone on reddit found the explanation: --- quote from reddit [1] --- Somehow some setups/regions run into a MTU black hole with Ubisoft Connect through Proton on Linux. Enabling MTU probing (for the techies out there, rfc4821) will fix this automatically. Lowering the MTU manually works as well. --- end of quote --- I tested this with NetworkManager and it worked: 1. run in a terminal: nmcli connection modify <connection name> 802-3-ethernet.mtu 1452 2. set network off then on in NetworkManager GUI. 3. check that the interface MTU is changed in a terminal: ip link list To get the '802-3-ethernet.mtu' property name I ran: nmcli connection show <connection name> | grep 'mtu' The default value was 'auto'. I tried 1492 but it didn't work. 1452 did. I didn't test other values or enabling MTU probing. I think this makes the issue invalid in Wine.
