I had 1 TH/s trained on the DASH pool through Nicehash the other day to give the pool a little boost. No issues with DDos protections kicking in. 

Hey Jeff. I've checked the stratum and everything is working. Network glitch perhaps?

Yes, there is: Arbor Networks but at 300$/month out of our league for now.

Problem wurde behoben. Danke für's Bescheid geben!

Fixed using https://github.com/coinfoundry/miningcore/commit/4c54c313844c69e84591c544510527fdd27313d6

Update deployed. Not seeing rejects anymore.

As long as its submitted using the 0x prefix all should be fine.

Working on it.

Which miner is that?

Bezüglich discarded: "Discarded is a meaningless stat unless you're using getwork (and even then it only matters to the pool operator, not the miner). It is a 100% useless stat on GBT and Stratum. Discards are not rejects, they aren't even shares. It means your software had work prepared to hash but instead it discarded it in favor of newer/fresher work. You aren't wasting any hashes when your miner discards work."

Wir hatten diese Woche einige DDos Angriffe zu verzeichnen die sämtliche Pools negativ betroffen haben und sicherlich ihren signifikanten Anteil zu rejecteten Shares beigetragen haben.

Also wir haben jedenfalls keine 9 Blocks gefunden. Ich habe keine Ahnung für was der FoundBlocks Wert steht. Andere anscheinend auch nicht: https://www.reddit.com/r/BitcoinMining/comments/67u5qc/antminers_foundblock/

Ich sehe in den Logs das die Shares von einigen Minern rejected werden weil der Pool den Miner aufgrund einer inkorrekten Addresse gar nicht authorisiert hatte.
