I either have a lot of lag, die randomly, or disconnect altogether when trying to fight a dragon. Happened 5 times tonight. Download speeds seem fine, I believe its happening eso server side.
Frequent disconnects could also be related to using a dynamic IP address. Please verify whether or not you are using a static ip address and make sure to use a wired internet connection if possible.
If this does not help resolve this issue, please let us know. In addition, if you are experiencing a specific error when disconnected, please provide a screenshot of that error.
