--scan-time=7
--expiry 28

then save file press ctrl-s this will save the file then exit winscp then set yor miner config for d=65535 then just restart your miner you should see much better results it works for me.

1. how did you get WinSCP to work with open-embedded software of L3+? (I get closed unexpectedly after authentication) Putty SSH works
2. Does not scan-time and expiry work best for http, not stratum based work? YMMV, but see below.

Also there's a lot of poor and misguided advice on how the expiry, scan-time and queue settings actually influence the rejections you're experiencing.
A lot of these settings were made for HTTP communication and not the much more efficient stratum protocol*.

--expiry
This setting defines how long time it takes before a work share is declared stale.
It is not used on stratum servers, since stratum servers supply it with work shares.
Only exception is when the statrum server is broken, then the setting is used as a fallback value.

Recommendation: Leave at default setting. Server will supply a proper setting.

To verify above simply follow the opt_expiry variable in cgminer.c source file.

--scan-time
This setting defines how long time, in seconds, the client should spend scanning current active work.
Again a setting that is not used on stratum servers, since stratum servers supply it with work shares.
Only exception is when the setting is lower than the server supplied setting, then it'll potentially generate more stale work.

Recommendation: Leave at default setting, which is 30 seconds for scrypt.

To verify above simply follow the opt_scantime variable in cgminer.c source file.

--queue
This setting defines how many work items you minimum got waiting in queue.
It is only relevant to prevent downtime when the stratum server is too slow at serving new work shares.

Recommendation: Leave at default setting, which is 1.

To verify above simply follow the opt_queue variable in cgminer.c source file.
