GSA SER Issue

Hey looking for some help if anyone can, il inout my problem and the steps ive taken:

Im using GSA SER with SERocket linked lists, along with working private proxies from buyproxie that test positive for both google and anonymous.

My issue is:
When i launch GSA everything is going fine and i get a decent amount of submitted, and some of those translate into verified, but if i leave it running for more than a few hours all of my submitted will drop down to 1, and i will consistently get this error message in my log:

download failed (Return: -, SockError: Connection refused)

Ive tried increasing threads, decreasing threads. Im running according to SERockets PDF guide and using their search engine exclusively as they said.

Does anyone know what to do here?

Sounds like a proxy issue mate, from what I remember SERockets PDF guide was a total waste of time and its settings were counter-productive for high link output.
