Hello,

I need to include a CA certificate root in a IoT in order to communicate to a pythonanywhere server.

Which CA certificate root should I use? I've tried Let's Encrypt but didn't work.

Thank you, Jaime

Are you trying to connect to www.pythonanywhere.com or to a web app on PythonAnywhere? What is the domain name of the web app?

to the webapp, in this case jaimedcsilva.com I am tryint to avoid using the certificate for jaimedcsilva.com as I know it changes frequentely. So I have read that the Certificate root will last for at least some years before it changes again.

I've tried the certificate ISRG Root X1 and X2. But none of them worked. At this point I can't understand why.

Thank you, Jaime

What errors do you get with the ISRG X1 and X2 ones? It certainly looks like they should work if you're using the ones from the Let's Encrypt docs.

Oh, just to double-check -- you are connecting to www.jaimedcsilva.com rather than jaimedcsilva.com, right? The URL without the www. will fail -- it doesn't look like you have a naked domain redirect right now.

CA:BD:2A:79:A1:07:6A:31:F2:1D:25:36:35:CB:03:9D:43:29:A5:E8 //SHA-1 ISRG Root X1 BD:B1:B9:3C:D5:97:8D:45:C6:26:14:55:F8:DB:95:C7:5A:D1:53:AF //SHA-1 ISRG Root X2 F0:AB:27:34:60:99:B4:80:18:67:45:57:76:DA:E0:EE:8F:C7:77:1A //SHA-1 jaimedcsilva.com

Hello,

From the above certificates only the jaimedcsilva.com works...

I've tried without the www. but then not even jaimedcsilva.com works.

I'm going to create the redirect and see if it could be related to that.

Thanks for your replies, Jaime
