I am experiencing problems where I get prompted with the following message on Android when visiting the site with Chrome:
No certifcate found. (image)
SSLLabs rates my website encryption as grade A.
The address to the server is:
The following code is used to set up the SSL context in python:
cert = ‘/etc/letsencrypt/live/snippetdepot.com/fullchain.pem’
key = ‘/etc/letsencrypt/live/snippetdepot.com/privkey.pem’
ssl_context = ssl.create_default_context()
ssl_context.verify_mode = ssl.CERT_OPTIONAL
web.run_app(app, ssl_context=ssl_context, host=‘184.108.40.206’, port=‘443’)
The prompt also occurs on Android with Samsung Internet and on Mac OS with Safari. It does not seem to be a problem on Linux while using Firefox or Chrome.
Changing fullchain.pem either chain.pem or cert.pem does not seem to make any difference.
Any ideas of how to solve this?
