How do I resolve a rsHttpRuntimeError in Internet Explorer when trying to run reports in AvaTax?


You are not able to export a report in HTML format and the following error appears:

An error occurred in the HTTP Runtime object for application domain ReportServer_MSSQLSERVER_0-749-130592420854775443. Most likely, the HTTP request contains an unsupported verb or invalid syntax. (rsHttpRuntimeError) 
For more information about this error navigate to the report server on the local server machine, or enable remote errors
