Hi GD Support, Today our dashboards are especially slow and many have the message 'Sorry we can't display this visualization'. Please help if possible.

Hi! Sorry to hear you're experiencing this. Based on similar reports in the community, here are the most likely causes and steps to investigate: 1. Check for a Known Platform Incident First, visit the GoodData status/announcements page to see if there's an active incident affecting your region. Past incidents have caused widespread slowness and visualization errors across dashboards. [Cloud Issue Example] 2. Investigate the "Can't Display This Visualization" Error This error can have several causes: • LDM/mapping issues: If recent changes were made to the data model (renamed attributes, changed mappings), visualizations can break. Open the LDM editor and check the mapping tab for any warnings on the attributes used in your insights. [Dashboards failing – LDM label issue] • Access/security restrictions: The message can also mean the visualization is restricted by access rules (

ProtectedReportSdkError

). Check whether data access filters are preventing users from viewing certain insights. [Dashboard errors] • Data limits exceeded: If a visualization returns more than 500 MB of data or exceeds 100,000 rows (without a metric), it will error. Try opening the visualization in Analytical Designer to see if a limit error appears. [Dashboard Freeze Case] 3. Investigate Slow Queries • Open a slow visualization in Analytical Designer and replace

/edit

with

/debug

in the URL — this downloads the exact SQL GoodData runs against your database. • Run that SQL directly on your database to check execution time, heavy joins, or timeouts. • Try removing metrics one by one to identify which is the heavy driver (the first metric acts as the SQL "driver"). [Performance Debugging] 4. Check for HTTP/1.1 Connection Limits On large dashboards, browsers limit concurrent requests to ~6 per domain. If your hosting environment only supports HTTP/1.1, requests queue up and cause slowness. The fix is to ensure your server supports HTTP/2 or HTTP/3 (e.g., by placing a CDN like CloudFront in front of your app). [HTTP Limits Thread] 5. Collect Information for Support To help GoodData Support investigate further, please gather: • Trace IDs from the Network tab in browser DevTools during a slow/failing load • A HAR file captured from Chrome DevTools during the issue • Exact timestamps (with timezone) of when the issues occur • Whether the issue affects all users or specific ones, and all dashboards or just some As a quick test, try loading the same dashboard in Firefox — if it works there, the issue may be Chrome-specific. [Support Investigation] Feel free to share Trace IDs here so the Support team can investigate further! 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups. 👀 Our Support team monitors all messages and will jump in if needed.

Hi Greg, could you please provide a link to a dashboard displaying the issue? Is this happening on all dashboards or just a select few?

It seems to have improved a bit so I think we'll move on. Thx

ok, thanks for clarifying. If the issue persists, please let us know and we can take a look.

Thx. Will do. We are located in the US in case anyone else reports the same thing.
