Nicehash connection closed issue

[WantClue]

I got into an issue I might think.
As soon as the pool vardiff changes the miners close the connections.
I use nicehash miners for testing purposes and have a monero pool.

To be seen in this picture as soon as changes happen connections seem to close. Same effect if a new block is been added and a new template has been sent out.

Did anybody experience anything similar?

This is after a new block template has been found. Normally the EOF should represent me that the miner has an issue and not the pool if I'm not mistaken but is there any changes that need to be made so that miningcore is operational with nicehash ?

Changed the name of this disucssion.

Issue still persists. Nicehash miners close connection if new job is been broadcasted and/or new block found and therefore new template is been send
