I'm experiencing an issue with Thunderbird that started unexpectedly. Whenever I try to access my email, I get a warning message saying that "The site certificate is not valid for this server. Someone may be trying to impersonate the server. It is not recommended to proceed."
I'm not sure why this error has suddenly appeared, as everything was working fine before. I haven’t made any changes to my email settings or installed new software recently. Has anyone else encountered this issue or knows how to resolve it?
