It seems you have a problem with the hostname resolution.
try to add your hostname/ip adress mapping to your hosts file
Sorry do not know what you mean by "hostname resolution". I am using the ip-adress to my TVServer and I have exactly the same settings in ver 1.1.5 and in that version all works OK.
I think it seems strange that the error log is talking about MySQL but I am using MS SQL as database engine in the TV server.
