Yes, testnet was reset, but we didn't create a new genesis block - it is still one mined at 2014-01-25 --> https://test.explorer.dash.org/bloc...75e2ec92894837288a481e5c005f6563d91623bf8bc2c
Normally the client should find peers by itself after some minutes, if you still have problems you can add the masternodes available: https://test.dashninja.pl/masternodes.html#mnlistdetail
Thanks for the info!
Using those masternodes as "addnode" fixed my problem!
I'm now up and running as a liquidity provider!
