An error occurred during a connection to tpz.sashacare.com. SSL received a record that exceeded the maximum permissible length.

Using firefox 140.6.0esr on Windows 10 with noScript and uBlock Origin

Infrastructure for my health insurance provider website uses a self-signed certificate. The infra has a different URL from the main page and was initially failing with "CORS failed", which turned out to be the cert issue.

I copied the infra URL from the dev tools network log and opened it directly, and accepted the invalid cert. I can see the new exception in cert_override.txt.

Then, after unblocking the site in uBlock origin, POST and GET requests to the infra URL succeed, but OPTIONS requests are still failing with "CORS failed", and security status "SEC_ERROR_UNKNOWN_ISSUER"

Is there anything else I can do so the OPTIONS request honors the exception in cert_override.txt?

I just got a Netgear router. Firefox won't let me connect because of the self-certification. I can only get on the internet via my Proton VPN. How can I fix this?

Specifically, I get this message--The certificate is not trusted because it is self-signed.
