hello again,sorry dear c.k.,i did hard reset for both my antminers and my router.but unfortunately the problem is still immutable.i tested 3333 and 443 ports,changed the btc addresses and used all 3 of btc addresses like segwit and legacy and...but the miners status is showing "DEAD" yet.please any suggestion...

thank you

I don't know, but there's probably a routing problem between where you are and the pool is. I've had one miner from Iran report the same thing to me elsewhere, so perhaps some places don't route properly to where the pool is.

If you're on linux you can check your routing with the following command:
mtr --report -w solo.ckpool.org

Additionally you might try solo4.ckpool.org or solo6.ckpool.org instead of solo.ckpool.org . Possibly it is trying to route through IPV6 and failing.
