After two years of running a website (https://emocoes.org), today for the first time it does not open on Safari. It opens on other browsers (Firefox, Chrome, Chromium, Opera), but on Safari I see:
Safari Can't Open the Page
Safari can't open the page "emocoes.org" because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait for a few minutes and try again.
Following Safari cannot open the page because the server stopped responding , I refresh the page, but see the same error.
The NodeJS logs do not show any GET request from Safari, and they do show them from Firefox. I clear the cookies and the cache from Safari and get the same error. If I open the page in a private window, then I can access the website, but I still need to fix this error for users who access the website on Safari. If the problem is specific to Safari and macOS, I will move the question to Apple.StackExchange.
What is the problem and how can I fix it?
update
Without having made further changes, the website is still failing on the same tab of Safari, and it works on the same instance of Safari but on a different tab. So the problem was likely from my computer and I will consider a reinstallation.
If it works in private browsing then it's something to do with your instance of Safari. As per your update, this seems like a local issue not a server issue!
