The issue here is discrepancies between certain voting sites and your votifier. Not much can be done since they dropped support completely for this resource, which sucks because it's a widely used one. I recommend you use whatever can receive a vote without throwing a process error. Vanilla V1, or current V2 protocol enabled sites seem to be the only kind that work for 1.8-1.12 servers. Confirmed list of sites that currently work for 1.8-1.12: http://www.eyeofender.com/ https://top-minecraft-servers.com/ http://minecraftservers.org/ http://minecraft-mp.com/server/157967/vote/ If you know any other sites that work for sure, please let us know!
