Apologies for the inconvenience.
I’ve checked the issue on your site, and it appears that the problem might be related to the font file generated by the web font converter at fontsquirrel.com . Sometimes their generated packages can cause issues during upload, especially if the file structure or metadata isn't fully compatible.
Could you please try generating the webfont using an alternative tool like https://transfonter.org ? It often provides better compatibility and allows more control over the file formats and subsets.
Let me know if the issue persists after using Transfonter, and I’ll be happy to assist further.
