This one seems environmental, perhaps github-related issues, but we should check regardless if it's possible to address this on our side.

[dennisrijsdijk]

It appears affected users are being hit with a ratelimit error by github for "scraping" the file.

Yes, got this same error last night after a succesful boot earlier the same day and I haven't been able to boot ever since. Tried rebooting + resetting my router just in case and it still continues today. I'm using v5.64.0 Linux DEB version on Linux Mint 22.2 Cinnamon.

Yesterday Firebot finally managed to boot. I suppose the rate limit issue on GH's side was fixed by then, but it may very well happen again. Does Firebot have to scrap the font every boot or is that unintended behaviour?

[zunderscore]

That behavior is intended. We cache the list of available Font Awesome icons for use in certain Firebot features (e.g. customizing Quick Actions on the Dashboard).

This issue has been resolved in our current dev branch and will be released in the next update.

[Kojirremer]

It's rate-limiting and refusing to boot once again.

It's rate-limiting and refusing to boot once again.

The update with the fix has not yet been released. We're still working to get it released.
