--- Comment #20 from Olivier F. R. Dierick o.dierick@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.
