Issue with the safari browser


Hi everyone,
I have encountered an issue configuring letsencrypt on my website with ngnix web server. While all the config seems right and also nginx does not complain for any error we seem not to be able to serve our contents for the safari users specifically and also our app side for apple phones. Rest works fine and no issue. I did search left right and the center of this site along some other places to find a clue for my problem and all failed to work it out for me. Appreciate any suggestions or insights.
We were the old user of the lets encrypt and recently just changed the locaction of the server.

My domain is:

I ran this command: “certbot --nginx certonly” from

My web server is (include version): nginx

The operating system my web server runs on is (include version): ubuntu 16.04

I can login to a root shell on my machine (yes or no, or I don’t know): yes



Could you please tell us what’s the issue?

Thank you


Hi, Safari on mac and ios cannot load the website , ios app can’t connect to APIs either.



Your website load correctly on my Galaxy note 9…
Do you have an error message? And do you mind to also share us a screenshot of the error message(if there’s any)?

Thank you


Your site seems to be fine:

Without any detailed error message, we can’t tell you anything useful.


Please see below…


I’m not seeing it? Could you please elaborate?


Hi Osiris,
The issue is this: after a lot of troubleshooting we came to conclude that in all OSs and Browsers the site works perfectly fine; and even the online certificate checkers find no issue …it is only the safari browser and IOS app that complain and do not load the site.
While watching the access.log and error.log in nginx, we can see that requests from Safari source IP come and few 200 but it never reaches to where the data transferred and completed


Hi @sinaghz

there is one error, Chrome has a warning:

Your document starts with

<!doctype html>

But this element is case sensitive. doctype is undefined, it must be

<!DOCTYPE html>

That may be the problem.
