Some of my rigs have this issue with optiminer

[error] TLS handshake with eu1-zcash.flypool.org failed: certificate verify failed

How to resolve it?

Works fine here. You are probably missing one of the root certificates that the pool uses. You can try 'openssl s_client -connect eu1-zcash.flypool.org:3443' to see what your system thinks about the pool certificate.

Thank you for V 1.6. Moved my 280x rigs over and a good bump on the Fuji's and 290's.

It fails to connect to the pool. Not sure why. Does it work with other pools?

Try this
optiminer -s eu1-zcash.flypool.org:3333 -u t1cCsQhjhFi8ZDbQNZB6tVEJaeBEQ1B7.swq7 -p x -m 8080

This is mine.

Hello,

What speeds do you receive from  v. 1.6.0?

Not sure what your settings are or the cards or OS but sometimes you have to increase the power to the card that isn't as good as the others. This happens because the miner is pushing the card more it sometimes can't handle the extra demand. In windows using afterburner, increase the mV to the core. I have once rig that has six of the identical cards but there is one card that can't quite handle the under volt like the rest. So, I turn the mV up a bit for all of them and its runs rock solid. Its worth a try at least until we have more information on your setup.

Initially, I had a couple of crashes with 1.6 (RX470 rig, Ubuntu 16.04), but now it is stable at least for 24 hr.
Crashes seemed to happen when I had firefox open at the same time.
No open browser-no crashes.
Quite peculiar if true, i wonder if anyone else observed the same with any browser.

is there a way to disable a gpu in a multi-gpu system?

[batut]

optiminer -s equihash.eu.nicehash.com:3357 -u 1DrxTn6Nn9NDjkBoy7Ug9w5LXWvGjKbe4j.voron -p x -i 5 --watchdog-timeout 40 --watchdog-cmd rebootoptiminer.exe
is it correct?

Then rig CRASHING.

[Onespec]

Optiminer, Please add option  RESERVE POOL.
Without this option, my rig falls and crashes if one losing the connection to the server pool.

GPUs undervolted. And if they don't hashing -  gpu driver crash and Rig  crashes.
It's a problem.

is there a way to disable a gpu in a multi-gpu system?

yes you can specify which gpu's are active.  You put -d 0 -d 1 -d 2, etc for all the active ones.  At least I think its -d.  Pretty sure if you run a bat file with --help or -help or -h..etc then you'll get the list of all available commands.

PLEASE help to setup  Run.bat settings to recconect to another pool server,
when Main pool is off and don't response.

What command  to reconect to another pool?

With Optiminer you need "zstratum://" prefix before the pool address. Like: zstratum://eu1-zcash.flypool.org:3333. If you mining securely: zstratum+tls://eu1-zcash.flypool.org:3443

No, you do not need ""zstratum://" prefix before the pool address". You only need it if you are connecting with "tls", as in your second example. Mine:

optiminer-zcash -d 0 -s nexus:9999 -u testie -p x -i 7 --watchdog-timeout 5 --watchdog-cmd ./watchdog-cmd
