I have a weird bug in 1.35 with flexpool.

When it happend:

01:03:07 [2021-12-29 15:05:57.006] Have not received data from pool for 20 seconds
01:03:07 [2021-12-29 15:05:57.006] Stratum thread exited
01:03:07 [2021-12-29 15:05:57.016] Pool connection disconnected or timed out

In the next period of time, I will get continuously invalid share like this:

01:03:08 [2021-12-29 15:06:41.204] GPU4 Solution found in 10.71s (Submit every 16.72 seconds)
01:03:08 [2021-12-29 15:06:41.234] Rejected (5755/5756) Reply: 23ms
01:03:08 [2021-12-29 15:06:41.234] mining.submit: Pool reponded with error
01:03:08 [2021-12-29 15:06:41.234] Error(-2): Invalid PoW Solution

The period may keep 17 ~ 19 min, make me 50+ invalid shares.

If not in this status, my rig has no any invalid shares.

I am sure not a connect problem, because my other rigs are working correct in the same time, and the gminer is never happend.

Please fix it,
