This fix worked for me. After previously getting the 218 error every time, I am now able to join Ranked matches after moving the install folder to my SSD from an HDD. however introduced some slowdowns in the waiting rooms. However, I now am able to load into Ranked matches, and the actual games seemed to run the same. Still have the leavers penalty, but didn't affect my ability to get into a Ranked match quickly.
Im suspicious about it being storage hardware related; as I can load up maps in solo Fleet Battles vs AI in seconds. Its only when in multiplayer does it take ages to load the maps and kick me with the 218 error.
