Why My hashrate is low than local

i use a Stratum Proxy in order to use a socks5 proxy to connect site, but i noticed sometimes the acceped hashrate is low than local acceped hashrate about 1/5 - 1/4 (Rejected hashrate is low than 4%) .what can cause this situation? sometime i restart the proxy or miner the hashrate could trun normal.

%both use proxy or direct connect cant avoid this problem

%i use asic miner(A4)

%my password is set 'g=dynamic d=32768'

%the delay i connect to pool is 300ms - 550ms i cant reduce it, my high speed proxy cant connet pool(proxy IP:103.75.117.208), proxy show the ERR: Subscribe response timeout.

if youre going through 2 proxies youre gonna have latency, which will result in lost shares. try using the regular stratum

also remove that g= command its not needed

Remove both, neither are needed with an A4.
So you connect the A4->Stratum Proxy->SOCKS5->pool, is that correct?
Do you manage the SOCKS5 proxy?

Yes, but my network situation is very bad, i'll set up an openwrt router to use a shadowsocks proxy tomorrow to see if it can fix the problem
