Hello @formMan , thanks for posting.
Based on my research regarding your problem, It’s possible you’re using React Router.
If that’s the case try creating a _redirects file in the public folder with the content below.
/* /index.html 200
Once you are done redeploy and let me know if it works.
If the above is not the case kindly provide a repository of the site you are trying to deploy for me to help with the debugging.
Thanks.
