When DataTables fails to populate a table with data from the server API, it triggers a pop-up with a user-unfriendly error msg. Reloading the page will usually correct the error. However the user is not informed of this.
Implement custom error handling function instead of this default datatables behavior. When we experience a datatables error, we reload the page (without params, in case the user was trying to load e.g. `http://localhost:3035/?rows=1000` which is expected to fail as the API will not provide this many blocks).
If this fails to solve the issue, next step would be to get the required data manually from an API call -- where we can control the `try...catch` behavior -- then load the table only when we have good data, e.g. https://datatables.net/examples/data_sources/js_array.html
