Questing bot gets disconnected after minutes of running

I am getting disconnected from honorbuddy server when I run the questing bot to level my new dk, I have stable internet connection, I constantly get the following error messages, then the bot gets stucked and stop.

The bot cannot be started when we are not connected to the server.

Disconnected from server, trying to reconnect..

Path distances request was canceled Path request received no response.

I've attached one of my log here, please help me.

 

I updated yesterday when I started the bot, and actually, these problems started for a month already.

yesterday when I started the bot, there was a update notice, and I did that

 

I updated the build to v3.0.17415.884, right after my toon picks up the quest item and run to the forge, I get the error
"disconnected from buddy service, try to reconnect..",
then "path distance request was canceled"
"path request received no response"
and when I restart the bot,
"The bot cannot be started when we are not connected to the server."

 

I did a clean install with the new 7.2.5 build using the zipped file, and the problem occurs more frequently than before

 

I am from macau, I play on the Taiwan server.

 

No, i changed it recently, I'm not using wireless anymore, before when I had wireless connection, the problem didn't happen as frequent like now

 

Problem still occurs, my other key has no problem running gather buddy, but the one I use quest bot my Alts can't even run for a minute, please help.

 

I flushed it many times already, disabling the firewall doesn't seem to help neither, it just disconnects every time I run it.

I don't know if it's because the test build is not stable or other cause, but the thing just keeps on happening.
I just want to bot.. D:
