Some of our users can no longer access our API hosted on azurewebsites.net.

When I go to https://<our-app-service-name>.azurewebsites.net/swagger/index.html I see the Swagger-generated page, but when some other visit the same URL they receive a response that the site uses an unsupported protocol:-

Your connection to the site isn't secure
ERR_SSL_VERSION_OR_CIPHER_MISMATCH

Why is this?

    Summarizing the discussion as an answer below so it benefits others in the community seeing similar issues.

    @Iain Harris @Rowland Shaw We had gotten similar reports from other customers today about this error. It appears that this was caused due to an ISP issue in the region, and is now resolved. More details here: https://twitter.com/ealexhudson/status/1434921204289351683

    Please check if you are able to access your apps again as usual.
