Text not showing on dynamic pages?

Question

css

Good afternoon colleagues!
I came across a problem of the following kind: building and working on the project locally - everything is OK, but on the server, when you go to the template page ( thymeleaf ), the text is not displayed until you do ctrl + f5 or uncheck any style on any element in the developer panel ( INTERESTING THAT THIS IS REPRODUCED IN CHROME AND OPERA I.E. V8 ) in all other browsers (FF, IE, Safari) everything is ok. If you comment out srcin @font-face, then the text is displayed normally, even without fonts.
If anyone has encountered a similar problem or has guesses about this, please respond and express your opinion on the possible reason for reproducing the problem.
Thank you for your attention
