Exactly, you're right. The problem is caused by the socks5 proxy supplied by HAProxy on local side doesn't enable the sticky-session option. I use another socks5 proxy exposed from HAProxy with the sticky-session option, and it does the trick: $ curl -x socks5h://127.0.0.1:18889 --ssl imaps://imap.gmail.com:993 --user "hongyi.zhao:passwd" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "Junk" * LIST (\HasChildren \Noselect) "/" "[Gmail]" * LIST (\All \HasNoChildren) "/" "[Gmail]/All Mail" * LIST (\Drafts \HasNoChildren) "/" "[Gmail]/Drafts" * LIST (\HasNoChildren \Important) "/" "[Gmail]/Important" * LIST (\HasNoChildren \Sent) "/" "[Gmail]/Sent Mail" * LIST (\HasNoChildren \Junk) "/" "[Gmail]/Spam" * LIST (\Flagged \HasNoChildren) "/" "[Gmail]/Starred" * LIST (\HasNoChildren \Trash) "/" "[Gmail]/Trash" * LIST (\HasNoChildren) "/" "&XeVPXJCuTvY-" * LIST (\HasNoChildren) "/" "&ZTZjbg-" * LIST (\HasNoChildren) "/" "&ZcWITHb4UXM-" * LIST (\HasNoChildren) "/" "&ecFOupCuTvY-" > I can connect fine.
