I logged in to my app and the TSL certificate has expired after 15 minutes. I renewed an expired certificate and I couldn't log in, however after clearing my browser's cookies I was able to login again.

My questions

Why did I need to clear browser cookies to be able to log in?

Are cookies somehow related to TSL certificate / (-es)?

Do old cookies become invalid upon TSL certificate expiration?

Are these issues specific to a given situation or is it a common behavior that an expired certificate makes a cookie invalid or is it something else (perhaps, app specific)?

CodePudding user response：

TLS certificates and cookies have nothing in common, they are totally independent. Cookies may contain encrypted data but that might be tied to some other certificate or private/public-key but this is still independent from the TLS cert.
