The one he posted was definitely a vaild bitcoin address. If he input it wrong into his miner, then solo would have just rejected him entirely.
We don't know if he is actually typing that address without any spaces, or a space in the url itself, or maybe using a wrong password, anyone who seeks support must at least provide
1- A screenshot of the miner status page.
2- A screenshot of the pool settings (you can hide a few digits in the middle).
3- Kernel log.
Without these 3 and without a magic ball, I don't think it's possible to help anyone troubleshoot their miners, some people are too lazy to post these things and all they say is that "my miner isn't showing on the pool" well, good luck.
Ease up turbo, I'm new to this and haven't had to ask for help on here before. Apologies for the lack of information.
I did have a random space in the URL itself which reported the pool Dead on the mining status page. Once I found it, the pool reported alive and the hashing started. After that, I checked for spaces in the address field and found none. The pool site says no password is required. If any of these were wrong, surely the pool would have rejected me straight away. Other people on here have tried to check my BTC address to see if any hashes had been reported by the pool and they haven't seen any either. I don't believe there is an issue with typing the address in to the URL or the box on the pool site.
I understand what you're saying about the kernel log but having verified the pool address and a valid connection on the mining status page, I don't understand why the pool wasn't seeing the miner. I'll try tonight and get those pieces of information if I still have no luck.
FWIW, I entered the nicehash configurations in exactly the same way and haven't had any issues.
[EDIT] just clarifying the point about the BTC address and the entry to the URL. Think I misunderstood what you meant about typing the address in.
