doSNOW and Foreach loop (R) on cluster?

Question

I am using a cluster to run a foreach loop in parallel, using doSNOW. The loop works on my desktop, I receive this warning when running on the cluster

Execution halted
Error in unserialize(node$con) : error reading from connection
Calls: local ... doTryCatch -> recvData -> recvData.SOCKnode -> unserialize

The loop is rather large, so I have just provided a very basic sample here (I do not believe the error is in the loop, as it works on the desktop).

library(sp)
library(raster)
library(fields)
library(tidyr)
library(dplyr)
library(sphereplot)
library(dismo)
library(doSNOW)
library(parallel)

cores <- (detectCores()/2)/2
print(cores)
cl <- makeCluster(cores, type = "SOCK", outfile = "")
registerDoSNOW(cl)

FossilClimCoV <- foreach(i = 0:5,.combine = "rbind",
        .packages = paste(c("dplyr","dismo",
                            "sp","raster",
                            "fields",
                             "tidyr","sphereplot","doSNOW","parallel"
                            )))%dopar%{
  print(i)
  FossilTemp <- Fossils%>%dplyr::filter(Age == i)
  if(nrow(FossilTemp)>0){
      BULK removed for ease
      return(FossilTemp1)
  }
}

I'm not sure how to fix this error. I don't understand why it will not work on the cluster, but will on my desktop.

EDIT 1 I have now resolved this large error by changing from a doSNOW backend to doParallel.

library(doParallel)
registerDoParallel(cores=3)
*foreach loop*

However, I now have a new error:

Calls: %dopar% -> <Anonymous>
Execution halted

If I change the errorhandling to "remove" the foreach loop will always return an empty vector.
