@jack-liew Which kind of browser are you using? Could you please try Chrome or Firefox? AutoK3s UI is not support IE browser.

[jack-liew]

I use friefox and ms edge .

[JacieChao]

Firefox works fine for me. Could you please try to open the F12 to see what kind of error occurs in the Firefox Console?
@jack-liew How about trying http://localhost:8080

[jack-liew]

http://localhost:8080:
Loading module from “http://localhost:8080/ui/assets/index.cafcc866.js” was blocked because of a disallowed MIME type (“text/plain”).
Loading failed for the module with source “http://localhost:8080/ui/assets/index.cafcc866.js”.

https://127.0.0.1:8080
Cookie “_dd_s” will be soon treated as cross-site cookie against “https://127.0.0.1:8080/ui/” because the scheme does not match.

[JacieChao]

Which version of Firefox are you using?

[jack-liew]

my firefox version is :98.0.2 (64-bit)
edge 99.0.1150.55 (64bit)

thanks

[JacieChao]

I'm using Firefox 98.0.2(64-bit) but the UI works fine for me. Is this error occurring on your Firefox Console?

Loading module from “[http://localhost:8080/ui/assets/index.cafcc866.js”](http://localhost:8080/ui/assets/index.cafcc866.js%E2%80%9D) was blocked because of a disallowed MIME type (“text/plain”).

[jack-liew]

yes, the browser is same version,and the error as you said.

[JacieChao]

Which version of AutoK3s are you using?
I'm not sure about this issue now, I tested with windows 10 using AutoK3s v0.4.9, Firefox 98.0.2(64-bit), and the UI works fine.
Could you please also try Chrome on your computer?

[jack-liew]

yesterday I user autok3s version is 0.4.8, today update to 0.4.9.
Did I have other preparations that didn't do?
because I just did:
download the exe file,and changed filename be autok3s.exe,then running:autok3s.exe -d serve.

[JacieChao]

Hmmm..... I also download the exe file and ran with the same command.
How about clearing all cache for Firefox or using a private window and try again?

[jack-liew]

......in private tab, It's still view a blank page.
firefox console message is:
Loading module from “http://127.0.0.1:8080/ui/assets/index.cafcc866.js” was blocked because of a disallowed MIME type (“text/plain”).
Loading failed for the module with source “http://127.0.0.1:8080/ui/assets/index.cafcc866.js”.

did I need install autok3s-ui and kube-explorer?

[JacieChao]

It's curious why the browser changes the javascript type file to text/plain...
@ly5156 Do you have any ideas?

[jack-liew]

thank for your help!
I'll try to search the answer.
thank again.

@jack-liew
You can clear your browser cache and try refreshing your browser
chrome example:

@jack-liew You can clear your browser cache and try refreshing your browser chrome example:

To clear cache not worked.
when i F12 to Find the problem, it view message:
Loading module from “http://localhost:8080/ui/assets/index.cafcc866.js” was blocked because of a disallowed MIME type (“text/plain”).

https://developer.mozilla.org/zh-CN/docs/Web/HTTP/Headers/X-Content-Type-Options
Blocks a request if the request destination is of type style and the MIME type is not text/css, or of type script and the MIME type is not a JavaScript MIME type.

It looks like autok3s web server has a bug about MIME type.

Thanks

@jack-liew I think it's a problem with Windows registry configuration. Could you please try to modify registry config as the following comments to check if this issue could be fixed?

[jack-liew]

It's worked,Thanks,
but I don't think it be a good idea.

[JacieChao]

This won't reproduce on every version of Windows. I didn't reproduce it on my Windows 10 computer.
golang/go#32350 (comment) is a temporary solution.

We will deep dive to see how to handle this issue more conveniently.
