For Flypool encrypted stratum port is different.
3443 (Encrypted stratum is currently only supported by the Claymore miner)
Example: ssl://us1-zcash.flypool.org:3443
I did go from flypool to dwarfpool i can now say <3 dwarfpool 2.3H later so much better!
I swapped to dwarf a few days ago and love it too. I've also talked with the dwarfpool admin about adopting SSL/TLS connections. They are looking into it now.
