IronPDF's default rendering timeout is 60* seconds.
- Not setting a timeout, or having a render delay longer than the set timeout, will produce the above Timeout / Unable to Render/Error while generating exceptions.
To override the default setting, adjust the
<a href="https://ironpdf.com/object-reference/api/IronPdf.ChromePdfRenderOptions.html#IronPdf_ChromePdfRenderOptions_Timeout">RenderingOptions.Timeout</a> .
RenderingOptions.Timeout = 120; // seconds; RenderingOptions.RenderDelay = 30000; //milliseconds
