Github PowerUp not working anymore

[Fabrice Benhamouda]

We used the Github PowerUp for quite some time but it stopped working completely at some point last week. We disabled it and re-enabled it. We also removed personal preferences.

Now when clicking on the Github PowerUp and then "Edit PowerUp setting", nothing happens and Chrome (version 86.0.4240.80 on macOS) console indicates:

```
Failed to handle show-settings. {error: "no plugin handles this command", id: "55a5d916446f517774210004"}
Failed to get authorization-status. {error: "no plugin handles this command", id: "55a5d916446f517774210004"}

instrument.js:110 Error, timeout while initializing index iframe for https://github.trello.services/index.html?ver=06487f4b1cd0. Timeout=30000ms
```

Firefox displays similar messages. In addition, Firefox displays the following messages:

```
The resource from “https://github.trello.services/sentry.012d105c.js” was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff).
The resource from “https://github.trello.services/github.e819f7fc.js” was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff).
```

This is also true in Private Navigation Mode.

The issue seems to be solved.

Hi Fabrice, How did you resolve this issue? I have been seeing the same as of 10/20. Thanks!

[Fabrice Benhamouda]

The issue disappeared by itself. I do not know what caused it to disappear.

[Tim DenOuden]

Got it, Thank you anyways! 

For those who may be reading this later, I am seeing the identical issue with the same error messages in the web console for the GitHub powerup in Trello, those errors are how I found this page. I have attempted an clearing of all cookies, private mode, relogging in and a different browser. None of which have worked thus far for me.

I'm getting the exact same issue. This issue is not fixed! I upgrade chrome yesterday and not sure if that is related. I have chrome Version 86.0.4240.111 (Official Build) (x86_64)

I'm gonna raise a new issue and hope it gets looked at...

[Tim DenOuden]

I just raised one myself. its ticket: TRELLO-15964

The issue showed up today and I can't fix it. Tried clearing the browser (Chrome) cache, tried to reinstall the plugin - no luck.
