It does seem more prevalent with SSL transfers - the SHA256s of the files transferred vis http are correct (over several transfers) while there is always an always an error on the https transfers from the same site. Interestingly the problem only seems to come up on 'fast' connections - possibly something CPU related (cpu load exacerbated by SSL?). I'm still not sure why the TCP layer doesn't sort out the dropped packets though. # ftp -Vo- https://ftp.openbsd.org/pub/OpenBSD/6.1/amd64/bsd | sha256 440311305f27f0efcfcc88116299a21cb3f890fb91ee611c2a79cc9163e8fceb # # # ftp -Vo- https://mirrorservice.org/pub/OpenBSD/6.1/amd64/bsd | sha256 ftp: SSL read error: read failed: error:06FFF064:digital envelope routines:CRYPTO_internal:bad decrypt
