After a major patch, the launcher sometimes freezes at 0% or throws a generic error. First, verify the game files through the ESO launcher — Settings > Repair. If that doesn't help, clear the cache folder located in Documents/Elder Scrolls Online and restart the launcher as administrator.
Error 201 or 210 usually means the authentication servers are under load. Wait a few minutes and try again. If the issue persists, log out of the launcher completely, clear saved credentials, and re-enter them manually. Also check that your system clock is synced correctly — a time mismatch can break authentication.
Lag spikes in ESO are often caused by your route to the megaserver, not the server itself. Try these steps:
Random crashes to desktop usually point to memory issues or outdated drivers. Update your GPU drivers, then lower the texture quality one step and disable "Anti-Aliasing" temporarily to confirm the GPU isn't overheating. Check Windows Event Viewer for crash logs — look for entries matching the ESO process timestamp.
If your ESO Plus subscription renewal fails, the issue is almost always on the payment method side. Check that your card hasn't expired and that your billing address matches what's on file. Try removing the payment method and re-adding it. If you're using PayPal, disconnect and reconnect the account in your Bethesda.net profile settings.
UI freezes after an update almost always mean one or more addons are broken. Disable all addons via the in-game menu, reload the UI with /reloadui, then re-enable them one by one to find the culprit. Keep AddOnManager updated — it flags incompatible addons automatically.
