ERR_HTTP2_PROTOCOL_ERROR when load page.aspx running on IIS 10

I have a .net framework application running on IIS version 10.0.17763.1 hosted on an Azure Virtual Machine and sometimes my users are getting ERR_HTTP2_PROTOCOL_ERROR

This site can’t be reachedThe webpage at https://..../page.aspx might be temporarily down or it may have moved permanently to a new web address. ERR_HTTP2_PROTOCOL_ERROR

I have no idea how to debug and it's an intermittent issue

The only thing that is failing to load is the page.aspx, all the JS and CSS are loading properly.
