Deployment issues (React app)

I have a problem with a deployment I made, sorry for my english, and I will let simple info to see if anyone can tell me what I’m doing wrong. I am new on thi, so please be patient.

I created an app with react and next, i uploaded to github and then deploy it in vercel. Until then all good. I added a custom domain (for showing to my client) but the website do not show on Safari Browser. Error says “can’t establish secure connection”

To try solve it I add my custom fonts (some info on the web says it could be that) but still having the error

This is thge app 4print-last.vercel.app // qadigitalads.review

Hi @qa-digital-partners, welcome to the Vercel Community!

Sorry that you’re facing this issue. Did you face such issue on any other browser?

I’d recommend trying the custom domain on a browser window without extensions or turning off any firewall you might have to confirm that this isn’t specific to your system. Because I’m able to open the website without any issues.
