Reconnecting

The connection to the server dropped. Trying to pick the session back up.

Attempt 1 of 30 — next try in 0s

Session paused

This tab was disconnected to free server resources. The session is still held, so it can be picked up where you left off.

Could not reconnect

The server stopped answering and the automatic attempts have run out. It may still come back — trying once more costs nothing.

Could not resume

The paused session could not be restored. Reloading starts a fresh one; anything typed into this page and not yet saved will be lost.

This session has ended

This page was connected to a server that has since restarted, so there is no session left to rejoin. Reloading picks up the new one; anything typed into this page and not yet saved will be lost.
