Couldn't BOINC send version info when contacting the servers, in order to automatically get unblocked? I'd like to hand in a few results too but have no idea if the results are still desired. Another forum page states "All the models/workunits there have already been crunched.".
My result file names start with hadam3p_eu_9anc_1966_1_007828185_0 and they "Temporarily failed upload <...> connect() failed" although I just upgraded to BOINC 7.4.42.

Hello ard

The model that you mentioned, hadam3p_eu_9anc_1966_1_007828185_0, finished way back in 2012, with all trickles returned.
Also, none of the computers under your name are blocked.

The only model that you have running at present is an ANZ model, and that seems to be running normally.
