Hi i think i find something special exception.

If i use gminer in nicehash for grin29 works perfectly, but if i want to use it to miningrigrental for grin29 i receive this error:

my miner settings when i use normal nicehash (and works no problem):
--algo cuckaroo29 --server grincuckaroo29.eu.nicehash.com --port 3371 --user XXXXXXXXXXXXXXXXX.rig12 --pass x --api 3333 --pec 1

my miner settings when i want to use miningrigrental grin29 (Connection Error: Write timed out)
--algo cuckaroo29 --server eu-01.miningrigrentals.com --port 3322 --user xxxx.xxxxx --pass x --api 3333

i try without passowrd also, and with ssl also same.
