This isn’t your problem.
The best thing you can do in this situation is just to keep your server reasonably updated and secured.
At best for you, the client side of a request was running seriously outdated software, and at worst your server is simply being scanned for vulnerabilities by compromised devices connected to the internet.
Personally I lean in the direction of this being scanning, as I myself see these errors on a private development server, to which only I should ever have a legitimate reason to connect to, yet I see a ton of IP addresses mentioned by the error from around the world.

I was getting a similar error when I sent an HTTPS request from my computer in Iran to my server outside of Iran. Eventually I came to the conclusion that the problem is with our internet network (maybe government filtering) and using vpn solved the problem.
Therefore, I recommend testing with vpn.
Check your secrete key decoupling with other settings.ini file
your app secret is not linking with variable you set
This may sound simple, but I was struggling with this issue because I was attempting to access
http://example.cominstead ofhttps://example.com. It probably isn’t your issue – but it worked for me.
