Certificates for internal fitbit sites have an issue. Perhaps they expired? I didn't dig hard enough to see if it was the Lets Encrypt issues from earlier this month. Once I discovered that https websocket connections were failing, I lost interest in chasing the problem further.
This is causing problems connecting to the developer portal, along with issues with connecting to Pandora
https://https://035-v3-client.fitbit.com/
Someone could be trying to impersonate the site and you should not continue.
Websites prove their identity via certificates. Firefox does not trust 035-v3-client.fitbit.com because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.
Error code: SEC_ERROR_UNKNOWN_ISSUER

Thought about it more, and I suppose the chain could be self-signed on purpose? Cert chain might be OK from the perspective of my watch, then.

Apple neither trusts the cert either, check in the details for more information

That domain in theory is a non-public one using our own root CA. I don't think that is related to your specific issue.

Thanks, that makes sense.
The confusing part is that I've got both a Versa 2 and a Versa. The Versa 2 is new, and I cannot get it to connect to the developer portal without throwing the "Connection error 1006". I switched back to the Versa, and it can still connect to the portal just fine.
I can see that it is connecting to that 035-v3-client.fitbit.com host briefly multiple times before it throws the 1006 error.
