how to fix error :net::ERR_HTTP2_PROTOCOL_ERROR

Question

I'm making a application in .NET Core ,suddenly this error shows:

Failed to load resource: net::ERR_HTTP2_PROTOCOL_ERROR

and I cannot load my data from database.JSON have some problems. This is photo of this: https://i.sstatic.net/78sGc.jpg

I didn't change anything in my code, suddenly this happened and I cannot find solution. I read this: whats-the-neterr-http2-protocol-error-about but this didn't help. This is .Net Core fault ?

On every browser I have this problem

Answer 1

FWIW - it's related to the size of the JSON data being loaded. I'm getting it in Chrome on a Mac and don't have a fix. On Safari on Mac I get kCFErrorDomainCFNetwork error 303.
