Can you share an image of issue or what was done before issue occured, even some log file records about this issue? It would help a lot.

Are you getting a 404 when trying to go to a public link? Is this only happening with old public links, or only with new ones, or both?

[Shra25]

Not tried with new links because of already many people using the old links and I cannot update everywhere with new links.

I tried all of our own previously existing public dashboard and question links, and all of them worked.

Could you provide a screenshot with sensitive data scrubbed out to show us what you're seeing (or not seeing)? We'll need to figure out if there are any commonalities between the questions/dashboards that aren't working. Any javascript or server log errors that you can provide would also be helpful.

I had this same issue and it was actually a problem with one of the dashboard cards. After the recent upgrade it went a bit funky but the result was that the public URL was returning a 400 error.

After I removed this card, the report worked.

The preview looked like this:

But the actual display on the dashboard looked like this:

Couldn't quite pin down what the issue was but deleting and re-adding the card worked.

Closing, since without detailed logs or reproducible steps, it's hard to know what happened.
