Firebase Hosting - getting Insecure Connection warning with custom domain redirection

3
votes

I have a custom domain name redirected to a Firebase Hosting site, which worked fine for a month or two but now am getting an Insecure Connection warning when I visit the domain -

(domain name) uses an invalid security certificate.

The certificate is only valid for the following names: firebaseapp.com, *.firebaseapp.com

Error code: SSL_ERROR_BAD_CERT_DOMAIN

The https://(project name).firebaseapp.com link works okay.

The Firebase Console is showing Needs Setup for the domain status, though it seems to be set up properly with the two A records, the TXT record, and a URL Redirect record, and the domain is listed as Verified.

The only thing that might have changed was in starting to set up Google G Suite, which required adding another TXT record for domain verification - I think after that the site started showing the security warning. I tried removing the TXT records and readding them but it didn't help.

I wrote to Firebase support and they noticed that I had the wrong A records in place - my domain settings (with Namecheap) had the correct A records, but I also had a URL redirect record, which is apparently bad. Try https://www.ultratools.com/tools/dnsLookupResult to make sure you have the right values.
