<p>When my customers try to submit a ticket through the Web Widget (Classic), they receive this message: <strong>There was an error processing your request. Please try again later</strong></p>

<p>This can occur due to one of two issues:</p>
<ul>
<li data-list-item-id="e8c680e31b4979f4f935bdc9ed163d91b">The error may be due to a 401 <strong>(Unauthorized)</strong> error in the console. This means the <strong>Anybody can submit tickets</strong> feature is turned off. When this feature is turned off, you can't use the Web Widget (Classic) to submit a ticket. For more information, see <a href="https://support.zendesk.com/hc/en-us/articles/4408881989018-Enabling-anyone-to-submit-tickets" target="_blank" rel="noopener noreferrer">Enabling anyone to submit tickets</a>.</li>
<li data-list-item-id="e44cd7b51d908bafde2c91868b68d2413">
<p>This can occur if an end user tries to submit a ticket from the Web Widget (Classic) using a support address. If this is the issue, you see a 422 error in the Network tab with this message:</p>

<p>This is due to the anti-tracking blocklist provided by disconnect.me, which Firefox uses. Despite attempts to appeal disconnect.me's decision, this platform lists Zendesk as a tracker. As a workaround, use any of the other supported browsers.</p>
