All results are rejected by the pool. I tried to restart many times but that didn't help. It used to work in the same setting before.
This problem caused by recent network upgrades and if you are using old miners you will get the reject response which means your shares not accept by the pool. if you are using the minergate pool you have to use their official miner ( I tested 2-3 days ago and the last version of XMRig didn't work )
Try supportxmr pool, It has no problem with the last version of the XMRig miner.
