I suspect user and password is wrong.
Since that mining pool require an account, you need using that user name that you signed with!.
Most mining pool allows us creating a worker starting with "1" and assigning a password.
If your user name is "user" then use:
-u user.1 -p x
If that mining pool allow assigning a password then use that password instead of "x"
Check if port is correct!
that's about it
Is there some reason I can't connect to mergemining with BFGMiner (5.4.2)? I have no problems connecting with any other miner.
$ /usr/bin/bfgminer -o stratum+tcp://mergemining.com:9332 -u user -p x
This eventually brings up (which repeats endlessly):
[2017-03-19 19:59:35] No servers were found that could be used to get work from.
[2017-03-19 19:59:35] Please check the details from the list below of the servers you have input
[2017-03-19 19:59:35] Most likely you have input the wrong URL, forgotten to add a port, or have not set up workers
[2017-03-19 19:59:35] Pool: 0 URL: stratum+tcp://mergemining.com:9332 User: user Password: x
[2017-03-19 19:59:35] Press any key to exit, or BFGMiner will try again in 15s.
Thanks in advance.
