I can't get it to connect and mine at either of those 2 sites.
The url I'm using is: stratum+tcp://us-east.stratum.slushpool.com
Port 3333
myusername.worker1
pass 1234
I would prefer to use Nicehash but I'll take anything at this point..
What am I doing wrong?
Thank you for any advice

When I first started it there was a small bit of action. After a few seconds it stopped. Now nothing. I have 4 USB miners. They're showing activity but I'm seeing nothing on the website stats.

Is my command line correct?
bfgminer -o stratum+tcp://sha256.usa.nicehash.com:3334/#xnsub -u 1Aog93G1hgo5uJqxCDa9yXPQ3a32QMi4Pe.Worker1 -p x

Thanks for any advice.

UPDATE:
It's been 2 hours but the time on the site says only 4 mintues. before it said 6 minutes.

I'm getting this on occasion:
[2017-07-04 10:25:13] Pool 0 stratum+tcp://sha256.usa.nicehash.com:3334/#xnsub not responding!

First a little history.
When I first discovered Bitcoin I ran an app called Bitcoin Miner on Windows 10. Extremely basic using my Nvidia card. About 150 Kh/s. They would deposit my earnings once a week into my wallet. It's was actually a few cents. Can't remember exactly.
So I bought a Raspberry Pi 3 and 4 ASIC Miners and joined Slushpool.
I'm mining at about 2.9 Gh/s and I'm not making jack crap. Not even a penny a week.

I have Googled the hell out of it and I can not find exact instructions on how to set up bfgminer to solo mine.
Was I solo mining using the Bitcoin Miner app from the Windows Store? Why was that more profitable?
Does anyone have basic instructions to set up bfgminer for solo mining?
 
Yes, I'm very new to this and I know I will probably never see much money but it's a fun hobby.
I look at it like tossing coins into a digital change jar here and there. I'm just not making any coins right now..

Thanks for any info!
