What is the Conn/Encoding error?
This means Connection Encoding Problem. There’s NO need to worry at all, it’s only when it is not able to connect to that site at that point or when the site you are posting to is not a WordPress blog. You may see this error very frequently but there’s no need to worry until and unless you are getting a successful posting rate of less than 15-20% as it is a part of the program. To have less encoding problems, use the Recommend number of threads.(Please refer to above questions), also you may try harvesting a fresh URL list.
