#metoo xD
eu does not respond at all, main gives jobs above my gpu ram limit (4gb) and i cannot set to static (expanse or nekonium) cause it shows there is no such coin available to mine

Still having huge connection losses, also one of my friends (other city, other provider, ...)

tcping -t eu.prohashing.com 3339
