So I have a website (let’s call it domain.com) and also an api subdomain for that (api.domain.com). When I try to access my website from any device it works perfectly fine. However, when I try to open the website from my old mac, I encounter two problems:
-
Certificate is not valid. For some reason on my mac this certificate is considered invalid, even though on EVERY other device it is (FYI about 30 people are already using this web app and they haven’t encountered any problems with the ssl certificate yet)
-
Besides certificate being invalid, I get php version page instead of index page, and any other /endpoint that my website has does not work at all and it says not found if i try to access it.
So far I’ve figured out that:
- This is not a browser problem, since I tried chrome, safari, vivaldi. The problem persists in all of them
- I also tried curling the url via terminal, and I also got some kind of error
- I use MacOs Big Sur, and my software update says that everything is up to date, which makes me think that it is probably due to some kind of ssl certificate miscounfiguration (even though ssllabs shows that my domain.com certificate is rated as B and api.domain.com is rated as A+).
What could be the problem here?
