All my azurewebsites.net default domains stopped working this morning.

Adam Brown 21

I use .azurewebsites.net domains for a bunch of internals of various web apps.

This morning, none of them can be loaded or contacted in chrome - I get ERR_SSL_VERSION_OR_CIPHER_MISMATCH.

@Adam Brown Thanks for reaching out and reporting this. I've reached out to our internal teams to check on this and will let you know as I have more details.

@Adam Brown Meanwhile, could you please confirm the SKU your apps are on? And the regions they are deployed to?

Hi,

This is azure app service apps, from multiple subscriptions. We typically leave internal APIs on azurewebsites.net addresses, so all calls to internal apis from mobile and desktop devices are failing for us.

Basically, it's impossible to make any https request of any *.azurewebsites.net address right now (not just mine) - they all fail with ERR_SSL_VERSION_OR_CIPHER_MISMATCH
