Hey, we had some server downtime yesterday and on the weekend sorry for that. I heard from many people that since yesterday they didnt face lobby disconnects anymore. If you still do, feel free to ping me here.
If you are still facing issues, especially when you are located outside of the EU (but connecting to eruope servers), try flushing your DNS cache.
