I find the solution on reddit.com

Just to point out, I have seen a few people recently who are logged on to the NA servers despite the fact their launcher says EU.

Go into Launcher settings, change to NA and then change back to EU and do a repair, this fixed it for the people I know having this issue.

There is a way to know for sure if you are logging on to NA or EU. Go to:

J:\Zenimax Online\The Elder Scrolls Online EU\game\client

Of course your directory letter may be different, but in this folder there is an .xml called "Platforms.xml". If you open this you will see:

<?xml version='1.0' encoding='utf-8'?>
<platforms><platform><name>Live-EU</name>
<login_service_url>https://live-eu-services.elderscrollsonline.com</login_service_url&gt; <realm_service_url>https://live-eu-services.elderscrollsonline.com</realm_service_url&gt;
<default>true</default>
<sleepy_giant>true</sleepy_giant>
<python_services>true</python_services>
<default_realm_id>4001</default_realm_id>
<use_login_queue>true</use_login_queue> </platform></platforms>

Make sure your realm_service_url and login_service_url are both "https://live-eu-services.elderscrollsonline.com". If not then you are logging on to the NA server.

Hope this helps!
