> Nothing super obvious. I see several connections from SLAC. The log shows some aborted/interrupted connections from INFN. The server will block further connection attempts from a client after 50 failures (a limit set in the config). This value is fairly reasonable for an externally visible server. We pretty much disable this behavior (set a high limit) for on-site servers. I just did a flush hosts on the server (the external one) to reset this. Might be worth a retry.
