Seems that after OpenSSH Server update after infamous Heartblead bug, Im allways getting these errors when copying / moving files within SFTP built in mc:

COPY/MOVE FILE TO REMOTE: ""-31: SFTP Protocol Error""
REMOVE REMOTE FILE/DIR: ""-31: Failed opening remote file""

Although after I press ENTER - operation continues successfully, however when transfering lots of selected files I have to acknowledge (press ENTER) on every file operation, so batch copy / move / remove operations are inefficient.

Doing verbose CLI sftp connection to the same server, succeeds without errors.
Also to note that to speed up transfers in ssh config file I prioritised blowfish protocol, what is honoured by sftp transfers, but NOT with mc sftp, as with sftp CLI (specifying blowfish) I get allmost twice the speed, but mc sftp transfer speeds are similar to the ones when I force AES encryption on CLI sftp."	defect	reopened	minor	4.8.21	mc-vfs	master		-31 sftp error chiper	graham@…			merged	committed-master
