The project is deployed to its own server and does not display the font

After the project is deployed to your server, the font is not displayed. There is no problem in the placanvans preview project. Please help solve it. Thank you.

Is the font bitmap file in the exported build? (msh1.png)?

There is a known issue where fonts which require multiple texture atlases are not correctly downloaded. Web Download - Font Issue

At the moment the best approach is to download the additional font texture atlases (they are named filename1.png, filename2.png, etc) and include them in your published build manually.
