I have an ASP.NET MVC (Framework) application that loads resources such as JS files using the following command:

@Scripts.Render(“~/bundles/jquery”)

Sometimes, I encounter the following error: Failed to load resource: net::ERR_HTTP_1_1_REQUIRED. This issue seems to occur randomly.

I provided the example with jQuery, but the problem could happen with any other bundle, such as Summernote.

I should mention that the resources are hosted locally, not on a CDN or any other external source.

If you have any ideas or suggestions, I would greatly appreciate it. The most challenging part is that this issue is so unpredictable…

Thank you in advance for your help.

I tried to disable HTTP/2 on my IIS server but without success. In any case, this wouldn’t be an ideal solution.

Best regards,
