SSL Cert No Longer Working

[eidylon]

What is the problem? Firefox won't connect, with the screenshotted issue. Opera gives a more generic error. Chrome gives an error too, but will allow me to bypass it. I'm guessing in the ever evolving world of internet security browsers are requiring higher encryption keys on certs, and the one in OctoPi is too low? But just a guess. Wondering, would it be possible to get OctoPi to integrate with LetsEncrypt now that that's a thing, so its cert is always valid and up to date? Don't know if it would be possible because of "domain ownership" checks by LE, but maybe somehow?

What did you already try to solve it? Can bypass the error in Chrome (for now) but not in Firefox or Opera.

FYI - for anyone else who might have the same issue, this seems to have fixed it, for Firefox anyway.

Corrupted certificate store

You may also see certificate error messages when the file in your profile folder that stores your certificates cert9.db has become corrupted. Try to delete this file while Firefox is closed to regenerate it:

Note: You should only perform these steps as a last resort, after all other troubleshooting steps have failed.

1. Open your profile folder:

• Click the menu button, click Help and select Troubleshooting Information. The Troubleshooting Information tab will open.
• Under the Application Basics section next to Profile Folder, click Open Folder. Your profile folder will open.

2. Click the Firefox menu and select Exit.
3. Click on the file named cert9.db.
4. Press Delete.
5. Restart Firefox.

Note: cert9.db will be recreated when you restart Firefox. This is normal.
