Of course.

All ports of all pools use vardiff (variable-difficulty), which means there's a starting difficulty (7500 in case of port 3032) which gets assigned to all miners after connecting. The pool constantly monitors the rate of submitted shares per miner and if the rate is too high, the pool sends the miner a higher difficulty. If the rate is too low (too few shares per 15 seconds), the miner gets assigned a lower difficulty. This auto-tuning process repeats endlessly.

I mean which port and location for user "Monero".

And Monero?

Which port are you connecting to and from which geographical region?

Go to https://coinfoundry.org/pool/eth and click the "Blocks" tab.

Thanks a lot Osos!

Your current amount of shares is 66 Million. I'm still working on the problem.

Miners 0xBdfbd97e6Ea30c491240748725106B1566ea8636  and 0xf2bc861c35082fa123598fe4eceeb04285c94e92 had mined long before you and accumulated much more shares over time than you did in the shorter time you've mined even though your hashrate was higher. The picture would be quite different for future blocks where other miners didn't have a headstart.

Welcome aboard, and no you weren't affected.
