Sorry if this is the wrong place for this topic, but there´s an issue I run into when I try solo-mining Grin through nicehash, using the default stratum server.

When I test my pool on nicehash, I get the following message:

Pool host: _._._._  
Pool port: 8516  
Pool user: henkvandam  
Pool pass: x  
Algorithm: GrinCuckaroo29

Resolving pool host _._._._… **OK**  
Establishing connection with proxy… **OK**  
Establishing connection with pool _._._._:8516… **Error: null**  
 _Your pool is shown as incompatible therefore we encourage you to contact pool operator to make sure that the pool is using minimal/starting pool share difficulty which is compatible with our service (and thus compatible with today’s miners), please send them following link: [https://www.nicehash.com/help/which-mining-pools-are-supported](https://www.nicehash.com/help/which-mining-pools-are-supported). Thank you!_

Anyone have a clue what could be going wrong?

Hello,

first, never a good idea to share your username!

second, we need more info:

- are you using a VPN…
- Are you using a Router (that points that port to your device that is hosting the ‘proxy’)…
- Did you try to connect externally to you IP address? (use something like: [https://www.ipfingerprints.com/portscan.php](https://www.ipfingerprints.com/portscan.php))
- (most importantly) do your miner SUPPORT nicehash? they have a slightly different stratum…
