Usually, when you cannot log back into a campaign by getting infinite loading screens times and times again, that means that an aoe fight is still happening near the position where you crashed and is lagging the server considerably (between 1k and 10k ping). Your only option is to wait until the two aoe groups stacking on top of each other decide to unstack to help the awesome aoe cap calculation process to catch up and to stop spamming meteors and standards so those particles don't have to register on every client present.
