For a long time, my typical connection process went: try a default server, time out on that effort, try (what I interpreted as) dns pool, connect successfully every time. I assumed this meant that there was a server pool and if you connected there, you got whatever in the pool was available. Today, I timed out on 4 successive servers and then the effort was automatically cancelled. I just installed v58, but it did not help to re-install earlier versions. This continues to happen.

Any suggestions? Thanks

If the connection process was cancelled after four attempts, this usually means that your Options/Connect/Options/Retry settings are set to only retry a connection four times. You should try increasing the retry connection value.
