https://49.248.86.238/ this is url my server

not working from outside network can you help me

I can connect to it, but it’s using a self-signed certificate.

Either everyone who uses your service will need to accept your self-signed certificate (and this probably rules out iOS and Android clients), or else you’ll need to replace it with a proper certificate, such as a Let’s Encrypt certificate.

Is that with a Let’s Encrypt certificate?

No I am using self assigned certificate

I don’t think that will work on Android (or iOS).

Okay you mean if I want to use outside access then I need to install Let’s Encrypt certificate I am right??

Okay I will try to install Let’s Encrypt certificate
An check it again thank you

I have installed Let’s Encrypt certificate but same error showing
See the below picture

According to the screenshot, the connection is “not secure” - it’s not using the Let’s Encrypt (or any other) certificate.

Where from I get certificate ?
Can you help me out this issue
Can you take my pc remote and check ?

You have said you’ve got the certificate, from Let’s Encrypt.

What web server are you using?

Nginx
