Sia/Decred Luxor Mining: Error submitting solution - Unauthorized User

[drobakowski]

Hi @robvanmieghem,

thanks for your work on this miner! I was playing around and tried to use it for mining Sia and Decred on a MacPro but unfortunately I don't get credited for my hashrate/share nor will it be shown on any mining pools like siamining, nanopool or luxor. I've installed gominer and I'm able to start gominer successfully wit the following command:

I'm not sure if there is maybe a problem in communicating with the stratum server or have I missed something? I've also tested my MacBook and got the same errors. Where Luxor at least can find my address but shows 0 MH/s, Nanopool an Siamining don't even find my address at all.

@drobakowski Thank you for reporting this issue, For nanopool, this is normal as they have a weird stratum protocol which they are adapting: https://github.com/robvanmieghem/gominer/issues/29 , siamining should definitely work as I test it there myself, I'll try to find time later today to see what is wrong with luxor.tech and revisit the authorization code for siamining. Btw, what processor do you have? Those Tahiti cards are perfect, that can not be the problem., I used Tahiti's when I created the first version of gominer.

@robvanmieghem thanks for taking the time to look into it. I'm using 2 x Intel Xeon E5620 @ 2.40GHz CPUs.

I don't get any error in console while mining for siamining.com, but even after a day I didn't get any valid share for my address according to siamining.com homepage.

gominer mining for siamining.com:

...

siamining.com stats for my address even after a day:

This address has not submitted any shares yet. If you have just started mining, please come back in a minute.

Looks like this relates to the same problem as with luxor.tech.

i have found the save problem with siamining.com that stats can not sync for

This address has not submitted any shares yet. If you have just started mining, please come back in a minute.

while gominer shows
