Is stratum+ssl still not well supported? Doesn't seem to work with zergpool
I don't think Zergpool supports it. I'm not aware of many pools that do.
on their front page says they do.
-o stratum+ssl://<ALGO>.mine.zergpool.com:<PORT> -u <WALLET_ADDRESS> [-p <OPTIONS>]
though it might not be working and the pool operator doesn't know it.
you have a better chance of finding out on their discord.
