HTTP2_Protocol_Error

Team

While using https with IIS we are intermittently getting ERR_HTTP2_PROTOCOL_ERROR on Dev tool in Production env.

This works fine with http protocol (QA). We are using IIS 10.

We are using React Framework 16.11.0 version and the fetch method fails.This happens in all the browser (edge, chrome etc) See attchment.

Sharing below the net log data.

{"params":{"description":"Server reset stream.","net_error":"ERR_HTTP2_PROTOCOL_ERROR","stream_id":183},"phase":0,"source":{"id":2567,"start_time":"1619763469","type":1},"time":"1619779275","type":222},

Please let me know if I need to share any other info.

Thanks in advance
